Neopentane

Vedclass · Answer

(D) The correct answer is $(d)$.Neopentane $(CH_3-C(CH_3)_2-CH_3)$ cannot be prepared by the hydrogenation of an alkene (olefin).In neopentane,the central carbon atom is bonded to four other carbon atoms,making it a quaternary carbon.For an alkene to be hydrogenated into neopentane,there would need to be a double bond involving the central carbon atom.This would result in the central carbon having five bonds,which is chemically impossible as carbon can only form a maximum of four covalent bonds.

Which of the following alkanes cannot be prepared by the hydrogenation of an olefin?
