I can do chin ups but not pull ups. Why?

This is because our body uses back muscle and biceps partially when we do chin ups. Whereas for pull ups our body depends more (like 90%) on our back muscle alone and hence doing pull-ups seems tough compared to doing chin ups.
This also means that you need to build a bit more strength in order to be able to do pull ups. Stick to chin-ups until then.
