Problem 3P
Write Lewis structures for the following molecular formulas.
(a) N 2
(b) HCN
(c) HONO
(d) CO 2
(e) CH 3 CHNH
(f) HCO 2 H
(g) C 2 H 3 Cl
(h) HNNH
(i) C 3 H 6(one double bond)
(j) C3H4 (two double bonds)
(k) C3H4 (one triple bond)
Solution:
Here we have to draw the Lewis structure of the following molecules.
Step 1
(a) N 2
The atomic number of N is 7. The electronic configuration is, 7N 1s2 2s2 2p3
The total number of valence electrons in N2 is = 5(2) = 10
The Lewis structure is,
