Hi Aarti,
As the verb 'haïr' (to hate) has what we call, un h aspiré ( h aspirate), we don't make the liaison to show that it is there.
Here are a few examples :
Ce sont des héros = They are heroes. ( the 's' is not pronounced)
J'adore les haricots = I love beans. ( the ''s' is not pronounced)
Il y a une très belle vue en haut de la colline= There's a beautiful view from the top of the hill.
Hope this helps!
