Which of the following bonds can form between atoms of equal electronegativity?
(a) ionic
(b) covalent
(c) hydrogen
(d) van der waals

(D) Van der Waals

Explanation:

Van der Waals forces -

They are the bond that are formed between atoms of the equal electronegativity .

Van der Waals forces are defined as the distance between any two atoms at where the forces becomes repulsive than being attractive .

The process is the resultant of the mutual repulsion between the atoms' electron clouds .

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of c is as shown here in the image.

the answer would be a
