R U mad or any thing else PhD in chemistry is nothing to do with MBA and MCA......there are totally Different Branches........MCA - 3 years , MBA -2 years PhD - 4 years these are the duration of these Courses........you cant do PhD unless You have a M.Sc in Chemistry honors so dont Post Such type of

IMO, its better to be a master in one trade than jack of all. and especially when you are planning for doctorate level. I would suggest you to go for either MBA or MCA and Phd in same field.
