Chemistry Bonding Covalent Structures

Question

Write the following elements structural formula, electron dot formula, molecular shape, bond polarity (P or NP) and Molecular polarity (P or NP)

Elements: H2O2, HCOOH, HCN, CO(NH2)2 , N2H4, C2H4, NH4+, C6H12

Answer 1

Chad,

I just did a bunch of these in your previous question, so I'll do one and you should be able to do the others.

HCN (10 valence electrons)

H - C ≡ N: Place C in the center and attach H with single bond and N with triple bond. Place 1 lone pair on N

Molecular shape = linear

Bond polarity = P

Molecular polarity = P
