Question

HC = C-CH=CH-CH3, Which carbon atom will<br />show minimum electronegativity:<br />(1) Fifth<br />(2) Third<br />(3) first<br />(4) Second​

Answer 1

Answer:

1 and 4 from left

Explanation:

Greater the s character, Greater the electronegativity.

triple bonded C atoms have sp configuration, which is 100/2 =50%

doubly bonded C atoms have sp2 configuration, which is 100/3 =33.3%

single bonded C atoms have sp3 configuration, which is 100/4=25%
