The reaction of toluene with Cl2 in the presence of FeCl3 gives 'X' and reaction in presence of light gives 'Y'. Thus, 'X' and  'Y' are

1. X = benzal chloride, Y= o-chlorotoluene

2. X = m-chlorotoluene, Y= p-chlorotoluene

3. X = o and p-chlorotoluene, Y = trichloromethyl benzene

4. X = benzal chloride, Y = m-chlorotoluene

Acetylenic hydrogens are acidic because

1. sigma electron density of C-H bond in acetylene is nearer to carbon which has 50% s-character

2. acetylene has only one hydrogen on each carbon

3. acetylene contains least number of hydrogens among the possible hydrocarbons having two carbons

4. acetylene belong to the class of alkynes with molecular formula CnH2n-2
