Why can't vinyl alcohols normally polymerize into polyvinyl alcohol? what happens then? Thank you in advance!
Homework Answers
Ans :-
Polyvinyl alcohol (PVA) is the synthetic polymer which is not directly obtained by vinyl alcohol like polyvinyl chloride (PVC) and Polystyrene. Because, vinyl alcohol is highly unstable and therefore easily undergoes tautomerism to convert in its stable form that is acetaldehyde.

Thank you in advance. Much appreciated.
Consider the dehydration of the following alcohols using a strong mineral acid as the catalyst and (a) place a circle around the alcohols that will dehydrate according to E1 mechanism, (b) place a box around the alcohols that will dehydrate according to E2 mechanism, and (c) place a triangle around the alcohols that will dehydrate according to both E1 and E2 mechanisms.

please show all steps thank you!
Vinyl chloride, C2HaCl, is a carcinogen which can be found in both air and water. a) If vinyl chloride is in the air at a level of 112 ppb, what is the mass concentration of vinyl chloride in the air? Assume T-293K, and P-1atm b) If vinyl chloride is in the water at a level of 112 ppb, what is the mas concentration of vinyl chloride in the water?

I know that Grignard reagents can react with alcohol, BUT why can't we generate a Grignard reagent from a molecule containing an OH functional group? Could you use an example or a mechanism to explain this concept?

Can someone help me with these? Thank you in advance!
1. The circuit shown here can't be reduced, since none of the resistors are connected in series or in parallel with each other. The unlabeled arrows show the direction of current in resistors 2, 4, and 5. Use Kirchhoff's junction or loop rules to answer questions (a)-(c) below. Show work for all calculations, and briefly explain your reasoning on current direction in (a) and (b). The symbols Ii, h, etc....

alerlahre 6. Esters react with water in the presence of acid to the generic reaction below). If you added water at the start of your reaction, what impact, if any, do you think it would have had on the amount of aspirin you produced? produce alcohols and carboxylic acids (see Н* R-OH +H20 R' R ОН R'
