QUESTION 16 How many double and single bonds are in the resonance form for S02 i

Question

QUESTION 16 How many double and single bonds are in the resonance form for S02 in which the formal charges on each atom are zero? o two single bonds and no double bonds o one single bond and one double bond o no single bonds and two double bonds o Each of these is possible. QUESTION 17 A A represents one lone pair of electrons o a double bond O a quadruple bond O two lone pairs of electrons QUESTION 18 The greater the electronegativity difference between two bonded atoms, the greater the bond order greater the covalent character of the bond greater the ionic character of the bond more unstable the bond

Explanation / Answer

Q16

Note that resonanc eimplies movement of electrons

Note that

O=S=O; O-S=O, O-S-O are all possibel, actually this is why there is resonance

so choose "each of these is possible"

Q17

A::A represent:

double bond

since there ar ea total of 4 electrons

each bond reuqires 2 electrons so

bonds = 4/2 = 2 bonds, i.e. double bond

Q18

if EN differenc eis large enough, they will become more ionic, i.e. more Cation/anion character
