Question 3 :
A molecule of hydrocarbon 'X' can add upon 2 molecules of $Br_2.$ 'X' on ozonolysis gives two different products which can not be further oxidised. Identify 'X'.

Question 5 :
A compound, containing only carbon, and hydrogenand oxygen, has a molecular weight of 44. On complete oxidation it is converted into a compound of molecular weight 60. The original compound is
