Hybridisation states of C in + CH and CH are (a) sp & sp

Hybridisation of carbon in + 3 CH is 2 sp and in 4 CH its hybridisation in 3 sp . 14. Heat of hydrogenation of cyclohexene is –28.6 kcal/mol and that of benzene is –49.8 kcal/mol. Then resonance energy of benzene will be (a) 46 kcal/mol (b) 39 kcal/mol (c) 36 kcal/mol (d) 30 kcal/mol 1 49.8 3 ( 28.6) 49.8 ( 85.8) 49.8 85.8 36 kcal mol x H H H
