Organic chemistry Quiz 10: Hydrocarbons derivatives and alcohols

#1. (9) It is preferable to prepare the alcohol by the hydrolysis of corresponding alkyl iodide.

a)Because the hydrolysis of alkyl iodide is easier than the rest of other alkyl halides

b)because the hydrolysis of alkyl iodide is cheaper than the rest of other alkyl halides

c) a and b

d) no correct answer

#2. (10) The boiling point of alcohols is higher than that of the corresponding alkanes.

a) Due to the presence of hydrogen bonds between alcohol molecules which are not found between alkanes molecules

b)due to the presence of pi bonds between alcohol molecules which are not found between alkanes molecules

c)due to the presence of sigma bonds between alcohol molecules which are not found between alkanes molecules

d) b and c

#3. (11) The boiling point of ethylene glycol is higher than that of ethanol.

a) Because ethylene glycol is dihydric alcohol while ethanol is monohydric alcohol and mor hydroxyl group increases the number of hydrogen bonds that increases the boiling point

b) because ethylene glycol is monohydric alcohol while ethanol is dihydric alcohol and mor hydroxyl group increases the number of hydrogen bonds that increases the boiling point

c) because ethylene glycol is dihydric alcohol and ethanol is polyhydric alcohol and mor hydroxyl group increases the number of hydrogen bonds that increases the boiling point

d) no correct answer
