Question

For phenol.. A.Using of polar protic solvents will stabilize the ground state energy level.B.Using of polar aprotic solvents will stabilize the ground state energy level. C. In nonpolar solvent, the wavelength is shorter than that of the polar aprotic solvent..D.Using of polar solvent will not affect the energy level because there is no interaction E. all F. None. 2.Regarding 1,3-butadiene: A. When unsubstituted, the excitation in cis-conformation requires less energy than trans-conform B. 4 sp orbitals form the n-system.C.When substituted by two phenyl groups the cis- conformation wavelengths become longer. D. When substituted, as trans-character increases as energy become. E. allD. None ​

Answer 1

Explanation:

: valence characterized by the transfer of one or more electrons from one atom to another with the formation of ions (as in sodium chloride and other simple salts) also : the number of positive or negative charges acquired by an atom by the loss or gain of electrons.

Answer 2

Explanation:

Acid radical is the ion formed after the removal of Hydrogen ion (H+) from an acid. Example: When H2SO4 loses H+ ion, it forms HSO4− which is an acid radical. The ion formed after the removal of hydroxide ion (OH−) from a base is known as basic radical.
