What is the representation of #"4-methylpent-2-yne"#?

Answer 1

You want the representation of #H_3C-C-=C-CH(CH_3)_2#?

Well this is #C_6H_10#. Each hydrogen contributes 1 valence electron, and each carbon atom contributes 4 valence electrons. There are thus 17 bonds (single and multiple) comprising these 34 electrons. You will have to count these up to check on me!
