I was going to throw in these problems in the next One Round Match, but it turns out 6th semester at IIT is pretty heavy and I don't get enough time to set up the contest website. So, here is a simple question for you. Choose ONE word/phrase which best explains the phenomenon:
Q1)Washing machine detergents are different from hand-wash detergents.
Q2)Life is all about replication (and duplication). So, life is carbon based and not silicon based.
Q3)Life is also about making and breaking bonds with oxygen. So, life is carbon based and not silicon based.
Note: 'Life' here refers to biological life (cells, DNA etc). And finally we have a chemistry question on the blog!
Here are the answers anyway:
ReplyDelete1)Washing machine detergents have a lower "Critical Micelle Concentration" which allows them to form micelles even in a large volume.
2)Carbon's "Catenation" properties give us the 'replication and duplication' required for life.
3)Silicon cannot just make or break bonds with oxygen (the bonds are too strong). Carbon can.
Cool.!
ReplyDeleteBhaiya please tell one thing that should we practice JEE papers Before 2006 Like Screening Papers or instead we should do timed practice of HPT and workshop!
ReplyDeleteI think that you have plenty of time to do both. The JEE screening exams take a lot less time i.e. the answers are very small.
Deletevipul what u think what we should do.
ReplyDeleteDo we Need To Mains Paper Also?
ReplyDeleteI think We should do screening papers but not sure abt mains i think all these questions are already put in module!!! In Form of some questions or the other!
ReplyDeleteThe previous reply was for shivam!!!!
