Question

what is the first alkyne atom? and tell how carbon present in that?? ​

Answer 1

Answer:

The first member of alkyne series is ethyne with two carbon atoms bonded by a triple bond; HC≡CH.

It consists of two carbon atoms connected by a triple bond, leaving each carbon able to bond to one hydrogen atom. Since both carbon atoms are linear in shape, all four atoms lie in a straight line.

Explanation:

Hope it will help you !!!

Answer 2

Answer:

first member of alkyne is ethyne. which is C2H2.

Explanation:

carbon and hydrogen are bonded with triple bond in this . in which two are pi-bond and one is sigma bond. these all three constitute triple bond. it has sp hybridization. ethyne is a linear molecule and each carbon atom makes two sigma bond and has no lone pair of electron.
