Question
Which statements are correct concerning the reason why acyl phosphates are more reactive to acyl substitution than esters and thioesters? Premise Response Drag and drop to match The lone pair/ orbital interaction is decreased because the electrons on the oxygen are distributed over the carbonyl and the oxygens on the acylphosphate A Incorrect PO4 is a weaker base and a better leaving group than RO and RS 2 - B Correct The phosphates' oxygens are more electronegative and decrease electron density on the carbonyl carbon making it more electrophilic 3 C Correct Phosphorus is larger than oxygen and sulfu There is increased overlap of the lone electron pair on phosphorus with the C-0 orbital compared to oxygen. The conjugation decreases the energy of the C-OT orbital. -D Incorrect ROPO is a weaker base and increases the-.^ activation energy of the elimination reaction a weaker base and increases the E IncorrectExplanation / Answer
Sorry questions in the first two images are confusing.
Isocyanate and amine reacts to give urea derivative
Diamine and diisocyanate reacts to give pictures
Alcohol or phenol and isocyanate reacts to give urethane
Diol and diisocyanate reacts to give polyurethane
