2. What are the general molecular formulae of alkanes, alkenes and alkynes (AS,) |
|
Answer» General formula for Alkane is CnH(2n+2) ; n is integer, n= 1, 2, 3…. For alkene it is CnH(2n) ; n = 2, 3, 4… For alkyne it is CnH(2n-2) ; n = 2,3,4… Since, alkene and alkynes refers to double bonded carbons & tripple bonded carbons respectively, there must be at least2 carbon atoms. |
