Question

(d) Give the structures of the polymers which can be formed from the following monomers.

Answer 1

d) i) CH₂=CH-CEN 1F CHE-CH- Acrylnitrile CNN CN Polyacrylonitrik (polymer) J-HI Lotion Polymer was to be mifo con-un-ckof-08-07 Polymer. Monomers on appropriate conditione gets polymerised to different polymers which have useful applications is daily life

14.a) x-amino and contains amino group at diftha-position, IR-CH-Cool R: H/ alkyl gp NH₂ in Hydrophobic Armino and contains non-plar fart CH₂-CH-Cool Alanine (1) Polar Amino acid contains polar side chain TEHEHE-HC - Cooh Glutamine NH2 NH2 (11) Acidic side chair Glutamic acid. 생 대대대에 NH Basic amino acid e Lysine HN NH2 5. a) Absence of flane of symmetry is necessary and sufficient condition for a molecule to be chiral.

chetty b) Anyar entre which is attached to to the t 4 different atoms is called chiral r y) I H a a i Centre. This centre produces different CICH E isomers (particularly enantiomers). d- isomer l-isomer thereby naming it a stereccentre Both rotate plane folarised light in Because of different stereoisomers opposite directions thereby guring foresence. Zero value of optical rotation. These are racemie mixture Racemic mixture Contais equd amout of (d) and (1) -isomers. Pair of Enantiomers *: stereocentre i) Butan-2-01 Only chiral molecules have sterecentre. contains sterevebe. Ćatom attached @ i) Enantiomers to 4-different catons. Afair of isomers having non-superimpo Chiral -sable mirror of each other are called enantiomers. C-a non-chiral achiral atoms Dame atunya H Enantiomers. irt) 2-Bromopropane. Br ii) Optical rotation. The rotation of CH3 CH3 =CH₂ same on both sides CH3 H 43 acherial flane polarized light by an optically iv) lactic acid active moleculle is called' CH₂ - CoolH optical rotation. 4 different groups are of attached chiral ist) Racemic mixture: A fair of v) citrie and isomers which rotate flane - ph Hooc- the - C- CH₂-COOH holarised light equally but in opposite direction are called racemie mixture. Achiral compound cool same same

vi) lemonene my chiral. Because it contains chiral carbon centre.
