Reimer tiemann reaction is an ideal reaction for the preparation of aldehydes.
here in this reaction the benzene reacts with phosgene , the both of chlorine atoms of phosgene are lost with H-atoms from both benzene molecules , and carbonyl group forms bond with both of the benzene molecules , giving rise to the Benzophenone. This is an important reaction in the synthesis of ketones only.

Here in this type of reaction the Copper is used as a catalyst and temperature of reaction is maintained at 573 kelvin. Primary alcohols give aldehydes and secondary alcohols give Ketones.
The oxidation of alcohols is an important reaction , the primary alcohols give aldehydes whereas the secondary alcohols give ketones. the reactions are as follows.
In case of aromatic acids the “COOH” group being electron withdrawing in nature , decreases the electron density on the ring. the meta position is least affected by the electron withdrawing group and thus the electron density is higher than other resonating structures. thus the substitution reactions give meta products.
Various carboxylic acids react with ammonia to give an ammonium salt which further give amid on dehydration. The phthalamide synthesized by this method is a starting point for various reactions used in chemical industries.
It is the splitting of spectral lines in hydrogen spectra due to the effect of external magnetic field .
a friend of mine, went on journey divine. gave no time, to say hi or good bye, hard on heart, to let him depart, yes he is apart, but struck like dart. we all can just say, for you we will pray. the cups we shared, the tips we paid. the moments we shared, all
In case of Esterification the nucleophile(centre loving specie that attacks on the electron deficit site) attacks on the carbocation intermediate formed during the reaction. The attack leads to the formation of a tetrahedral intermediate which on rearrangement(proton shift) and loss of water molecule, leads to the final product. the step-wise and easy illustration is given
It is the splitting of spectral lines into further fine lines due to the presence of external electric field.
