Dear patidarshm@gmail.com
 
In case of multiple questions within a query, please post each question individually and let us know where you are getting stuck so that we would be able to explain things better.
However, answer to your first query is,
In the structure of Glycerol, there are three hydroxyl groups attached which creates several hydrogen bonds with itself, making it more viscous.
