Question

Unshared, or lone, electron pairs play an important role in determining the chemical and physical properties of organic compounds. Thus, it is important to know which atoms carry unshared pairs Use the structural formulas below to determine the number of unshared pairs at each designated atom. Be sure your answers are consistent with the formal charges on the formulas. C NH2 The number of unshared pairs at atom a is-- N Thenumber of unshared pairs at atom b is a The number of unshared pairs at atom c is The number of unshared pairs at atom a is- HC b The number of unshared pairs at atom b is NH2 The number of unshared pairs at atom c is- Submit Answer Retry Entire Group 9 more group attempts remaining

Explanation / Answer

The number of unshared pairs at atom a is: 1

The number of unshared pairs at atom b is: 0

The number of unshared pairs at atom c is: 1

The number of unshared pairs at atom a is: 2

The number of unshared pairs at atom b is: 0

The number of unshared pairs at atom c is: 1

Explanation: oxygen has two lone pair of electrons and nitrogen has one lone pair of electrons and carbon has no lone pair of electrons.
