Ans given B. How do we judge these that will it form dimer or chain or something else. Or do we just learn it?
Is the answer A or B? @Soumyadeep
Oh,sorry.I thought it is the past year book.
Anyways,i am attaching the thoery part.
But,the polymerisation part is not given.
Yup,yaad karna padhega.
It is given in bottom right corner.
Kya yaad karna Padega? Its simple concept. Hydrolyse and remove water molecules
I mean ki, jaise yaha par dimerize bhi ho Sakta tha but linear polymer ban rha hai. Talking abt this thing.
Like it will have two OH after hydrolysis na, so can't it dimerize??
Ans is B @Supreeta_Sen
It will start with dimerizing but it will not stop and the chain will continue to grow so will result in a linear silicone
Bcoz the dimer has high scope of increqsing chain length
Exactly as Anish said
R3SiCl stops at dimer but whenever there is a scope of increasing or linking chains like in R2SiCl2, it happens
lp-lp > lp-bp > bp-bp
the first one contains one lone pairs on both the S atoms
the second conatins lone pairs only on one S atom
the third one does not contain lp on S atoms
