The Correct order of increasing bond length of C - H, C-O, C - C and C = C is
C - C < C=C < C - O < C - H
C - O < C - H < C - C < C = C
C - H < C - O < C - C < C= C
C - H < C = C < C - O < C - C
D.
C - H < C = C < C - O < C - C
C - H: 0.109 nm
C = C : 0.134 nm
C - O: 0.143 nm
C - C : 0.154 nm
Therefore, Bond length order is
C - H < C = C < C- O < C - C
Two elements A and B have the electronic configuration as:
A = 1s22s22p63s2 and B = 1s22s22p5
Write the empirical formula of the substance containing A and B.
What type of bonding would you expect between:
(i) a metal and a non-metal
(ii) a non-metal and another non-metal?
Give reasons in one or two sentences for the observation that in their compounds non-metals form anions and not cations.
