Oxygen is more electronegative than carbon, and thus pulls electron density away from carbon to increase the bond's polarity. Therefore, the carbonyl carbon becomes electrophilic, and thus more reactive with nucleophiles. Also, the electronegative oxygen can react with an electrophile; for example a proton in an acidic solution or other Lewis Acid. refer to http://en.wikipedia.org/wiki/Carbonyl

Why is ketones and aldehydes are called as polar compounds?
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
Does ethanol contains the carbonyl group?
No. Ethanol contains a hydroxyl group, but not a carbonyl group.
Why hydrogen bromide is electrophile?
hydrogen bromide is not the electrophile its bromide ion may act as the nucleophile, in alkyl halide the alkyl group may act as an electrophile.
What function group is found in an aldehyde?
Carbonyl
What is a carbonyl esters group?
In the field of organic chemistry a carbonyl group consists of carbon atoms double bonded with some oxygen atoms. However, Carbonyl Esters consists of carbonyl group influenced by different alkyl groups.
In cross aldol condensation between aldehyde and ketone why aldehyde is always an electrophile?
Alkyl groups are electron donating (whereas hydrogen atoms aren't). A ketone has 2 alkyl groups attached to the carbonyl carbon, but an aldehyde has only 1 alkyl group attached to its carbonyl carbon. This gives the aldehyde carbon more positive charge character, which makes it a better electrophile than the ketone. Another factor is less stearic hindrence for carbonyl carbon of aldehyde as compare to ketones.
Attraction between benzophenone and methanol?
The carbonyl group of the benzophenone acts as a hydrogen bond acceptor with the alcohol group of methanol.
What is a name of a key functional group found in carbohydrates?
carbonyl group

What element make up the carbonyl group?
A carbonyl group is a carbon-oxygen double bond.

What is the COH functional group?
The Carbonyl Group.
What is the functional group of glucose?
carbonyl group
Why do we call a nucleophilic addition as 1 2 nucleophilic addition or 1 4 nucleophilic addition?
1,2-addition occurs when the carbonyl oxygen (1) is attached by the electrophile and the carbonyl carbon (2) attaches to the nucleophile for the 1,4 the 4 is the beta carbon
