Question

Unshared, or lone, electron pairs play an important role in determining the chemical and physical properties of organic compoun 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 The number ofunshared pairs at atom a is HCThe number of unshared pairs at atom b is The number of unshared pairs at atom c is The number of unshared pairs at atom a is The number ofunshared pairs at atom bis-- The number of unshared pairs at atom c is aLi. -Al-H bH Retry Entire Group 2 more group attempts remaining Submit Answer

Explanation / Answer

Total number of valence electron pairs around O is 4. Among them; 2 are bond pairs.

So; number of unshared pairs of electrons around 'c' atom = 4-2 =2

Total number of valence electron pairs around Carbon is 4 and all are bond pairs.

So; total number of unshared electrons around 'b' atom us 0

Total number of valence electron pairs is 3 and all are engaged in bonding

So; number of unshared electrons around 'a' atom is 0

Li+ contains no electron in valence shell.So; number of unshared electron pair around 'a' atom is 0.

Number of unshared electron pairs around 'b' is 0

Also; number of unshared electron pairs around 'c' atom is 0.
