Answer 1

Answer #1

III C mechanism is correct mechanism.

let's look step wise,

this reaction is called keto-enol tautomerism.when acid is present, H+ ions protonate ketonic oxygen.

this will give C=O+H.

therefore opening of double bond of C=OH. resulting into carbocation at carbonyl carbon.

and thus pick up of beta hydrogen to carbonyl carbon and fromation of enol.

how many lbs of 10-10-0 fertilizer should i apply? Problem A1: Your soil test report said you needed 100 lb acre-i N and 30 lb acre-P,0. Your field is 0.5 acres. You have a bag of 46-0-0 and you have two bags of 10-10-0 (all bags are 100 lb each). What will you apply? Hint: Start with the 10-10-0 fertilizer since it contains two nutrients. Also, start with P because you will apply N with the P and usually applications...
