Question

what are the reactions and impotant physical properties of alkenes, haloalkenes, alcohols, aldeyhydes, ketones, acids

Answer 1

An important reaction would be From a primary alcohol to Alderhyde to a carboxylic acid, using K2Cr2O7/H+ (Acidified Potassium Dichromate) a Orange to Green colour change is witnessed. Alkenes have a two or more of the carbons bonded with a double bond and when reacted with a Halogen, such as Bromine the double bond breaks and the bromine bonds to each carbon around the double bond. Keytones have an oxygen double bonded to a carbon that is bonded to other carbons, and can be made my reacting a secondary alcohol with K2CR2O7/H+

Answer 2

I should say the Keytone’s carbon has to not be at the end of the chain and when the Alkene undergoes Halogenation with Bromine an orange to colourless change is seen

Answer 3

Properties- Alkene C=C, not sure anout Haloalkenes but Halogenoalkanes is a carbon chain with a halogen bonded to it. Alcohol is a normal chain with an O-H group attached, Aldehyde is a normal chain but with a double bond O on the end of the chain. Keytones were discussed before and Acids (If you mean Carboxylic Acid) have a Double bond O and an O-H group bonded to the end of the chain. (Normal chain here meaning one that all bonds between carbons are single bonds)
