Answer to Question #131835 in Inorganic Chemistry for Morgan

Question

3.2 Explain the following regarding carbon, with the aid of appropriate orbital diagrams:
(a) Draw the ground state orbital diagram for C, clearly indicating the electron occupancy of the p subshell
(b) Explain, with the aid of an appropriate orbital diagram, how CH4 forms
(c) Would the C─H bond be very polar, slightly polar or non-polar?
(d) What is the bond angle in the CH4 molecule?

Answer 1

a)

" C " have atomic number 6 having electronic configuration 1s2 2s2 2p2 .

After excitation this is orbital digram incorect ( before excitation ) correct ( after excitation ) .

b) .

c).

C-H bond is slightly polar due to very less electronegative difference .

d )

Bond angle is 109⁰.28^'.
