The anion formed after the removal of first H ⊕ of oxalic acid ( I ) is more stable due to stronger - I effect of - COOH present at close distance.

The anion formed after the removal of first H ⊕ of oxalic acid ( I ) is less stable due to + I effect of - COOH group.

The anion formed on removal of first H ⊕ of malonic acid is more stable than that of oxalic acid due to - m effect of other - COOH group.

Oxalic acid is more acidic than malonic acid due to its lesser molecular weight.

An alkene of molecular formula C 9 H 18 , on ozonolysis gives 2 , 2 - dimethylpropanal & 2 - butanone, then the alkene is

2 , 2 , 4 - trimethyl - 3 - hexene.

2 , 2 , 6 - trimethyl - 3 - hexene.

2 , 3 , 4 - trimethyl - 2 - hexene.
