The distance between carbon atoms in a diamond is 154 pm. What is the idstance between the carbon atoms in millimeters?

a. 7.7 x 10^-5

b. 7.7 x 10^-7

c. 1.54 x 10^-7

d. 1.54 x 10^-9

Answer:- The right Answer is d). 1.54 x 10^-9

Covalent radius is one-half of the internuclear detachment flanked by two bonded atoms (also called the bond length). Therefore, rC=12(154pm) =77pm.
