With an ester, excess Grignard is needed, because the first equivalent pushes out the leaving group, and the second equivalent educes the resulting ketone into an alcohol (after protonation by water).
Ter. alcohols are those in which alpha carbon (carbon bearing halogen atom) is attached to three other carbon atoms, in aldehyde there is only one and in ketones there are two carbons attached to alpha carbon so by hydrogenation aldehydes may be converted into primary alcohols and ketones into secondary alcohols so preparation of ter. alcohols is not possible. however ketones with Grignard's reagents may produce tertiary alcohols.
Aldehydes and ketones haven't an -OH group.
No, monomers and polymers of aldehydes and ketones do not have hydroxyl groups attached. Aldehydes and ketones have a carbonyl group (C=O) attached to at least one carbon atom and do not have any hydroxyl groups (-OH) attached to the carbon chain.
bORSCH REAGENT ALSO CALLED bRADY REAGENT .iT IS USED TO DETCT ALDEHYDES AND KETONES
No, their 'OH' groups are usually involved in chemical reactions.

The aldehydes and ketones having three or less carbon atoms are soluble in water.

Aldehydes and ketones
Aldehydes are less sterically hindered than ketones. Also, aldehydes have fewer electron donating groups (EDG's) which can stabilize an electron-poor area. The extra carbon chain that ketones have that aldehydes do not have are the reason for both of these things. The neighboring carbon to the carbonyl carbon is an EDG and the carbon chain causes steric hindrance.
Ketones or Aldehydes DO NOT react with Sodium Bicarbonate..generally only Carboxilic acids have the ability to do it!
Aldehydes and ketones haven't an -OH group.
alcohols, aldehydes or ketones, or carboxylic acids
A Silver mirror does not appear as ketones cannot be further oxidized unlike aldehydes in which a silver mirror does appear.
aldehydes n ketones contain a carbonyl group in which carbon is attached to an oxygen with a double bond. The carbon is less electronegative than oxygen therefore carbon acts as an electrophile and oxygen acts an a nucleophile. That is carbon is partially positively charged n oxygen is partially negatively charged. Hence aldehydes n ketones are polar compounds
