The internuclear distance between any tw...

The internuclear distance between any two carbon atoms in diamond is `154`p m, so the covalent radius of carbon `(r_(c))` is equal to

A

`154` pm

B

`308` pm

C

`32` pm

D

`77` pm

Text Solution

Verified by Experts

The correct Answer is:
D
Covalent radius is one-half of the internuclear distance between two bonded atoms (also called the bond length). Thus, `r_(C) =(1)/(2)(154"pm") = 77`pm.
