acyl chlorides NEED TO CHECK IN TEXTBOOK

Card preview (12)
when are acyl chlorides formed?
when -OH group in the acid is replaced by another atom/group (making them acid derivatives)
how do you name acyl chlorides
• oyl chloride
name the product formed when -OH in ethanoic acid is replaced by another atom or group
ethanoyl chloride
give 2 properties of acyl chlorides
clear fuming liquids at room temperature very reactive
why are acyl chlorides so reactive
the carbon doesn’t have enough electrons so holds on to carbonyl ( C=O) and releases Cl
is the product of the reaction between sulphur dichloride oxide and carboxylic acid pure?
no, will always have something in excess purify product by distillation separate the acyl chloride from any excess acid or thionyl chloride
when an acyl chloride reacts with a compound X-O-H (where x is hydrogen/an alkyl group/benzene ring what type of reaction is it? and what products are formed and why?
• HCl gas produced (H coming from OH and Cl from acyl chloride) • everything let over just gets joined together addition elimination reaction
describe the nature of the reaction of acyl chlorides and water and what are the products of this reaction
extremely vigorous at room temperature products: carboxylic acid + Hydrogen chloride gas (steamy acidic fumes given off)
what are the products of the reaction between an alcohol and an acyl chloride
ester and hydrogen chloride (HCl)
when an acyl chloride reacts with concentrated ammonia what products are formed
an amide + hydrogen chloride gas
when an acyl chloride reacts with an primary amine (cold concentrated solution in water) what products are formed NEED TO CHECK IN TEXTBOOK
a secondary amide + a quaternary amine
