Chp 19 carboxylic acid

Question 1

what does carboxylic acid compose of?

Answer 1

-COOH

Question 2

which oxygen is more basic/ acidic in COOH and why?

Answer 2

the C=O is more basic bc it has more electrons localized

the COH is acidic bc the O withdraws electrons from the H making it easier to donate

Question 3

how to name carboxylic acid if linear

Answer 3

replace the e in alkane and add -oic acid

Question 4

where is the C1 on a linear carboxylic acid

Answer 4

on the carbonyl carbon

Question 5

how to name carboxylic acid if cyclic

Answer 5

add carboxylic at end

Question 6

where is the C1 on a cyclic carboxylic acid

Answer 6

@ alpha carbon, one carbon away from carbonyl carbon

Question 7

in NMR, the H in COOH is ?

Answer 7

the most acidic, therefore the most deshielded, most downfield @11-12ppm

Question 8

alpha H’s are what in comparison to the H in COOH

Answer 8

less acidic than the COOH, therefore it will be the next most downfield usually @ 2-2.6
