The aldehydes and ketones have carbonyl group as the functional group. The carbonyl carbon sp 2 hybridized and thus has three sp 2 hybrid orbitals and one unhybridized p-orbital. It uses sp 2 hybrid orbitals to form three s -bonds one with oxygen atom and remaining two..

The halogen atom in haloalkane is replaced by nitro group (-NO 2 ) when it is treated with silver nitrite (AgNO 2 ) and give nitroalkanes. The bond between Ag-O is covalent and therefore, the nucleophilic attack here occurs through the lone pair on nitrogen: nitroalkanes (R..

Structure of the Carbonyl Group - The aldehydes and ketones have carbonyl group as the functional group. The carbonyl carbon sp 2 hybridized and thus has three sp 2 hybrid orbitals and one unhybridized p-orbital. It uses sp 2 hybrid orbitals to form three s -bonds one ..

. Methanol has a dipole moment of 1.71 D whereas phenol has a dipole moment of 1.54 D. The smaller dipole moment of phenol is due to the electron withdrawing effect of phenyl group in contrast to the electron releasing effect of alkyl group in alcohols. In ethers, the four elect..

This chapter contains oxygen compounds in which oxygen is bonded to a carbon atom through a double bond. The functional unit >C = O, present in these compounds is called carbonyl group. We limit our study now to compounds having an acyl group (R - C = O) is bo..

The two alkyl groups (R and R') may be same or different. When the two alkyl groups (R and R') are same, the ketone is a simple ketone. If the two are different the ketone is called a mixed keton..

C(n,r) is the required combination by definition. Each of these combinations consists of a group of r dissimilar things, which can be arranged among themselves in P(r,r) = r! ways. But the number of permutations of n different things taken r..

An ester contains the group COOR where R is an alkyl group. The hydrolysis of the ester gives the parent acid and so its name is based on the name of the aci..

Introduction - Cyanides are characterized by the presence of cyano (-CN) group in their molecules. They are considered to be the derivatives of hydrogen cyanide (HCN) in which H atom is replaced by alkyl or aryl group. If -CN group is linked to alkyl group, t..
