Answer 3

Single -> 1 sigma
Double-> 1 sigma 1 pi
Triple-> 2 sigma 2 pi

Question 4

Reasons for formation of cations

Answer 4

->lesser electron density and more proton density
->central atom makes more than its capacity (valency)

Question 5

Classify hydrocarbons with a mindmap

Answer 5

Open chain closed chain
Saturated unsaturated homo/heteronuclear
Alkane Alkene Alkyne

Question 6

Why are alkanes called as saturated carbons?

Answer 6

More H2 cannot be added to alkanes to form another compound unlike alkene and alkynes
