#1. (15) The solubility degree of glycerol in water is more than that of ethylene glycol and ethanol

a) Because glycerol is trihydric alcohol while ethylene glycol is dihydric alcohol and ethanol is monohydric alcohol And as the number of (OH) grou increases the formation of hydrogen bonds with water increases and solubility increases

b) because glycerol is polyhydric alcohol while ethylene glycol is dihydric alcohol and ethanol is monohydric alcohol And as the number of (OH) grou increases the formation of hydrogen bonds with water increases and solubility increases

c) because glycerol is trihydric alcohol while ethylene glycol is monohydric alcohol and ethanol is monohydric alcohol And as the number of (OH) grou increases the formation of hydrogen bonds with water increases and solubility increases

d)because glycerol is trihydric alcohol while ethylene glycol is dihydric alcohol and ethanol is monohydric alcohol And as the number of (OH) group decreases the formation of hydrogen bonds with water increases and solubility increases

#2. (16) Methanol is liquid and oxygen is gas- in room temperature - although their molar masses are equal to each other (32 g/mol)

a) due to the combination between methanol molecules by sigma bonds that is not present between O2 gas molecules

b)Due to the combination between methanol molecules by hydrogen bonds that is not present between O2 gas molecules

c) due to the combination between methanol molecules by pi bonds that is not present between O2 gas molecules

d)b and c
