If there are two or three multiple bonds in the parent chain, then the suffix -diene (for two) or triene (for three) are used respectively. The positions of the multiple bonds are indicated by the numerals indicating the carbon atoms at which multiple bonds start. The numbering of the chain is don..

When a molecule contains more than one similar functional groups, then, the word di (for 2), tri (for 3), etc., is added before the secondary suffix, of the functional group. While adding such words, the vowel 'e' of primary suffix is retained. For example: Here, Word roots = but Prefix =..

The number N A , given by N A = 6.023x10 2 3 mol - 1 is called Avogadro's number, named after Italian scientist Amadeo Avogadro (1776-1856), who suggested that all gases contain the same number of atoms or molecules when they occupy the same volume under the same conditions of temper..

In case is an integer, then T r+1 = T r and both T r+1 and T r are the greatest term..

Since the two decision variable x and y are non-negative, consider only the first quadrant of xy- plane Draw the line ax + by = c ...(1) For each constraint, the line (1) divides the first quadrant in to two regions say R 1 and R 2 , suppose (x 1 , 0) is..

Calculate the molecular formula of a compound with vapor density of 30 having 40% carbon; 6.67% of hydrogen and the rest is oxygen. Empirical formula = C 1 H 2 O 1 Empirical formula weight = 12 x 1 + 2 x 1 + 1 x 16 = 12 + 2 + 16 = 30 g Molecular..
