If two different chains of equal lengths (equal number of C atoms) are possible, then select the chain which has larger number of side-chains i.e., select the more-branched chain. For example, in the following molecule, there could be two continuou..

Generally a polymer sample contains chains of varying lengths and therefore its molecular mass is always expressed as an average. In contrast, natural polymers such as proteins, contains chains of identical length and hence have definite molecular ma..

A primary prefix is used to distinguish alicyclic (aliphatic cyclic compounds) from acylic compounds. A prefix cyclo is used before the word root if the compound is an alicyclic compound. For example, Cyclopentane:..

The boiling points of alkenes gradually increase with an increase in the molecular mass (or chain length). This indicates that inter-molecular attractions become stronger with an increase in the size of the molecule. Branched chain alkenes have lower boiling points th..

When the molecule contains two or more dissimilar functional groups, the parent chain is so chosen so as to contain maximum possible number of functional groups. The numbering of the parent chain is done so that the functional group of higher priority gets the lower number. The ..

When the ribosome has moved sufficiently down the mRNA chain towards 3 end, another ribosome takes up position at the initiator codon of mRNA, and starts synthesis of a second molecule of the same polypeptide chain. At any given time, the mRNA chain will, therefore, ca..

>All aldehydes and ketone with type group give haloform reaction. Carboxylic acids are prepared by oxidation of primary alcohols, aldehydes and alkenes, by hydrolysis of nitriles and by treatment of Grignard reagents with carbon dioxide. Aromatic carboxylic acids can also be prepared by side c..

>The two-polynucleotide chains run in opposite directions (antiparallel). One chain runs in the 3-5 direction. While for the other chain 3-5 direction is opposite. The average distance between the two chains is 20A 0 . One full turn of the helix, called gyre,..

Carboxylic Acids and its Derivatives - Introduction - Carbon compounds containing a carboxyl functional group -COOH are called carboxylic acids. A carboxyl group is constituted of two groups - a carbonyl group and a hydroxyl group -OH. Carboxylic acids may be aliphatic (R-COOH) or aromatic (Ar-COOH..
