a) sp -s(sigma), C-H b) sp-p(sigma).C-N c)p-p (pi), C-N
d) sp-p(pi).C-H​

Answer 1

Answer:

HCN has one single and one triple bond. The latter consists of a sigma bond from the overlap of a C atom sp hybrid orbital with a N atom p orbital, and two mutually perpendicular pi bonds are formed from parallel atomic p orbitals of carbon and nitrogen atoms.
