Answer 1

-- a) CH₂-2-0-CH2CH3 & b) erzth-CHech chilly what IR absorption would you use to distinguish between two compounds above ay CH₃-C-0-CH₂-CH3 . /1740-1760 cm I.R.) This compound is ethyl-methyl ester having Ester functioned group i.e. R-Y-O-R'.. These are simple esters and their carbony group trequency is approximately 1740-1760 cm? 1.2. Ester Cirbony group (CPU) absob 1740-1760 cm! frequeney, => by CH3 -CH2-CH=CH2=CH-CH₂ /3000-2850 cm / C-H streching => 1470-1450 cm C-H bending. compound is hercone Cice.n-thesline) caved alkane and shows C-H Streching and bending frequeney. Alkane i.e. hexane shows absorption band of die frequency in C-H streching is 3000-2850 cmy approseimately, and C-H bending frequency shows 6 1470-1450 cmt approximately
