Does methane undergo nitration?

Lower members of alkanes like methane do not undergo nitration at ordinary temperatures. Thus, because of the less reactive nature alkanes don’t undergo nitration easily.

Why lower alkanes do not undergo nitration and Sulphonation reactions?

Nitration or sulphonation of lower alkanes undergo via free radical mechanism. This is because the abstraction of hydrogen to form free radical in lower alkanes is much difficult as compared to higher alkanes because free radical of lower alkanes are less stable due to less inductive effect.

What happens when propane undergoes nitration?

Here, the major product that we find is 2-nitropropane and its yield is around 40\%. We can see from the above discussion that we obtain 1-nitropropane, 2-nitropropane, nitroethane and nitromethane from the nitration of propane. So, the correct answer is “OptionA,B,C and D”.

Is the reaction between methane and chlorine endothermic?

If more energy is put into a reaction than is given off, the ΔH is positive, the reaction is endothermic and not energetically favorable. Since, the ΔH for the chlorination of methane is negative, the reaction is exothermic.

Why methane or methane is not possible?

Methene and Methyne does not exist because they have only one Carbon atom and cannot form multiple bonds in their compounds and also hydrogen can share one electron.

What is molecular formula alkane?

Alkanes are organic compounds composed of single-bonded carbon and hydrogen atoms. The formula for alkanes is CnH2n+2. They can be categorized into three groups which are: chain alkanes, cycloalkanes, and branched alkanes. The most basic family of compounds has been called alkanes.

How does the sulfonation occur?

Sulfonation is a reversible reaction that produces benzenesulfonic acid by adding sulfur trioxide and fuming sulfuric acid. The reaction is reversed by adding hot aqueous acid to benzenesulfonic acid to produce benzene.

What is sulfonation and sulfation?

Sulfonation and sulfation are two important chemical processes used in many industries to add a sulfur-containing group to an organic compound. The main difference between sulfonation and sulfation is that sulfonation involves the formation of a C-S bond whereas sulfation involves the formation of a C-O-S bond.

How does methane react with HNO3?

Nitromethane is formed when methane reacts with conc. HNO3 at high temperature. Methane reacts with conc. HNO3 at high temperature to form nitromethane.

Can be produced through the reaction of propane and nitric acid?

1-nitropropane is produced industrially by the reaction of propane and nitric acid. This reaction forms four nitroalkanes: nitromethane, nitroethane, 1-nitropropane, and 2-nitropropane. 1-nitropropane is also a byproduct of the process for making 2-nitropropane, which is done by vapour phase nitration of propane.

Why the reaction between methane and chlorine is considered a substitution reaction?

methane (CH4)is a carbon compound that is alkane. alkane compounds generally do not react at all since they are quite stable. however when methane is exposed to sunlight, in a fast reaction, Cl can displace H from CH4. Since Cl can substitute H and form CH3Cl+ Hcl, this reaction is called substitution reaction.

Why methane does not undergo nitration reactions normally?

Methane belongs to lower group of Alkanes. They have no pie bonds. Absence of pie bond shows that electrons cannot move to undergo reaction. Therefore, lower alkanes, methane, do not undergo nitration reactions normally.

What is the mechanism for nitration of benzene?

The mechanism for nitration of benzene: Step 1: Nitric acid accepts a proton from sulphuric acid and then dissociates to form nitronium ion. Step 2: The nitronium ion acts as an electrophile in the process which further reacts with benzene to form an arenium… Step 3: The arenium ion then loses its

What is the rate profile of NIT nitration in concentrated sulfuric acid?

Nitration of less reactive substrates has to be studied in concentrated sulfuric acid. Originally, the shape of the rate profile in the 85–98\% sulfuric acid region for the compound under study was compared with those for compounds known to react as either the free base or conjugate acid.

What is the yield of nitromethane at high temperature?

But at very high temperatures (673°K) and high pressure NITRATION of methane has been observed with a very very low yield of nitromethane. Methane belongs to lower group of Alkanes. They have no pie bonds. Absence of pie bond shows that electrons cannot move to undergo reaction.
