How do you know if a compound exhibits tautomerism?(i) Compounds must contain polar molecule and weakly acidic functional groups. (ii) Tautomerism is the change of position of an atom. (iii) Tautomerism has no effects on bond length and other such features. (iv) Generally, tautomerism occurs...
A compound that does not have any polar bonds have a zero resultant dipole moment. Also, if there is symmetry in the compound that has polar bonds, the dipole moments of bonds get canceled and the compound has a zero resultant dipole moment. Answer and Exp...
The ammonia molecule is a nitrogen-containing molecule that has a zero net charge and has a lone pair on the nitrogen atom (the central atom for the molecule). The said molecule shows a trigonal pyramidal structure or geometry and is considered a polar molecule. The polarity of ammonia will...
