Answer 1

EXPLANATION:

2)There are 3 sigmas and 2 pie bonds for C2H2 (a)

3)C2H2 is Sp hybridisation there fore bond angle is 180.(b)

4)BECL2 Is Sp hybridisation.(b)

5)S character has 50 percentage in Sp hybridisation.(b)

6)There are 2 sigma and 2 pie bonds in CO2.(A)

7)BECL2,CO2,C2H2,belongs to Sp hybridisation.(a,b,c)

8)Sp hybridisation is also called as linear hybridisation, but according to option d he told that it is also called tetrahedral so option is (d).

9)according to option all the statements are important condition for hybridisation.(d)

10)according to the option all are the silent features of hybridisation.(d)
