Which one of the following substances is more likely to dissolve in benzene(c6h6)? a) naclb) ccl4c) nh3d) ch3ch2ohe) ehbr

B. CCl₄

Explanation:

Solubility is determined by the principle , "like dissolves like" .

i.e. , if a compound is polar then it will dissolve in a polar compound only , and

if a compound is non - polar then it will dissolve in a non - polar compound only .

Hence , from the question ,

Benzene is a non - polar compound , i.e. does not separate out into poles , and hence , it will get dissolved into the CCl₄ , as it is too non - polar in nature , according to the above theory of solubility.

Hence, from the question,

Benzene will dissolve in CCl₄ .

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."

sure im new too!
