#1.
(12) The boiling point of glycerol is higher than that of ethylene glycol.
a) Because glycerol is trihydric alcohol while ethylene glycol is dihydric alcohol and boiling points increases by increasing the number of (OH) group
a) Because glycerol is trihydric alcohol while ethylene glycol is dihydric alcohol and boiling points increases by increasing the number of (OH) group
b) because glycerol is trihydric alcohol while ethylene glycol is monohydric alcohol and boiling points increases by increasing the number of (OH) group
b) because glycerol is trihydric alcohol while ethylene glycol is monohydric alcohol and boiling points increases by increasing the number of (OH) group
c) because glycerol is trihydric alcohol while ethylene glycol is dihydric alcohol and boiling points increases by decreasing the number of (OH) group
c) because glycerol is trihydric alcohol while ethylene glycol is dihydric alcohol and boiling points increases by decreasing the number of (OH) group

d) because glycerol is trihydric alcohol while ethylene glycol is dihydric alcohol and boiling points decreasing by increasing the number of (OH) group
#2.
(13) The boiling point of sorbitol is higher than that of glycerol.
a)because sorbitol is polyhydric alcohol while glycerol is dihydric alcohol and the boiling point increases by increasing the number of (OH) group due to formation of hydrogen bonds

b) because sorbitol is polyhydric alcohol while glycerol is monohydric alcohol and the boiling point increases by increasing the number of (OH) group due to formation of hydrogen bonds
b) because sorbitol is polyhydric alcohol while glycerol is monohydric alcohol and the boiling point increases by increasing the number of (OH) group due to formation of hydrogen bonds
c) Because sorbitol is polyhydric alcohol while glycerol is dihydric alcohol and the boiling point decreases by increasing the number of (OH) group due to formation of hydrogen bonds
c) Because sorbitol is polyhydric alcohol while glycerol is dihydric alcohol and the boiling point decreases by increasing the number of (OH) group due to formation of hydrogen bonds
d) because sorbitol is polyhydric alcohol while glycerol is monohydric alcohol and the boiling point decrease by decreasing the number of (OH) group due to formation of hydrogen bonds
d) because sorbitol is polyhydric alcohol while glycerol is monohydric alcohol and the boiling point decrease by decreasing the number of (OH) group due to formation of hydrogen bonds
