In hexa-1,3-diene-5-yne, the number of `C-C sigma, C-C pi` and `C-H sigma` bonds respectively are:

Options

A. 5, 4 and 6
B. 6, 3 and 5
C. 5, 3 and 6
D. 6, 4 and 5

Answer

A

Explanation

`{:(H-overset(1)(C)=overset(2)(C)-overset(3)(C)=overset(4)(C)-overset(5)(C)-=overset(6)(C)-H),(" |"" |"" |"" |"),(" "H" "H" "H" "H),("Hexa-1,3-diene-5-yne"):}`
C-C, `sigma`-bonds=5
C=C, `pi`-bonds = 4
C-H, `sigma`-bonds = 6
