Question

the first member of alkane has one carbon atom but there is no alkyne with single carbon atom. why?

Answer 1

Answer:

if an alkyne has one carbon atom then, then one H atom must be bonded with the carbon atom using 3 bonds......

Since a hydrogen atom cannot have 3 bonds ...... so a member of alkyne series cannot have 1 carbon atom......

Similarly, a member of alkene series cannot have 1 carbon atom......
