Conditions for geometrical isomerism:
Compound will depict geometrical isomerism if it fulfils the subsequent two conditions
(i) There should be frozen motion as regards two adjacent atoms in the molecule.
(a) > c=c < frozen motion that is about carbon, carbon double bond in alkenes.
(b) Frozen rotation that is about carbon, carbon single bond in cycloalkanes.
(c) > c=N- frozen rotation that is about carbon, nitrogen double bond in oxime and imine.
(ii) Both of the replacements on every carbon could be different about which rotation is frozen.
If these two types of conditions are filed, then element will depict geometrical isomerism.
The compounds of the following type will not depict geometrical isomerism.
The ratio between the neutrons in C and Si with respect to atomic masses 12 and 28 is: (1) 2 : 3 (2) 3 : 2 (3) 3 : 7 (4) 7 : 3 Ans: 3 : 7
Q. Show the Ionization of Acids in Water? Ans. Like ionic compounds, acids are electrolytes . When dissolved in water, acids break down into ions. Ionization refers to
CACO3 CAO+CO2 IF CAO IS ADDED EXTERNALLY WHAT WILL BE THE CHANGE{WILL FWD REACTION INC OR BACKWARD REACTION INC}AND WHY ? Solution) Backward reaction, due to Le Chatelier''s

Classification of proteins - biomolecules As per to the chemical composition, proteins are categorized into two classes 1. Simple proteins 2. Conjugated proteins
While solving lime sida numericals we calculate CACO3 equivalent .In this we do conc. In ppm×100/mol. Wt. ssomewhere we multiply 2 × m. Wt .so wht 2
what is inductomeric effect
Q. How to determine wavelength of electromagnetic waves? The frequency as well as velocity of a wave determines its wavelength the distance between equivalent points on a con
diagonal relationship between Li and Mg
