Api bond is formed by
a. side-by-side overlap of two p orbitals
b. overlap of a p orbital with a f orbital
c. end-to-end overlap of two p orbitals
d. overlap of two d orbitals overlap of an s orbital with the end of a p orbital

c. end-to-end overlap of two p orbitals

Step-by-step explanation:

A Pi bond is a covalent bond established by two atomic orbitals overlapping side-to-side. The combinations of these two atomic orbit may be px-px or py-py. A pi bond can be bonding or antibonding, identical to the sigma bonding.

hence the correct option for the question is c. end-to-end overlap of two p orbitals

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
