Answer 1

a Electronic Electronic Coulsoura configuration given - 1st 2s²2pf i e. total no. of electrons a 10. Among the given options to has a total mo. of eletrons as 10. of a plus one due to negative change rect option (6) F(-) B. Chst in me In the given structure / compound Sodium forma an lome hond with oxygen, due to the wign electronegativity difference between the two (which is one of the baue irresia for lonie houding). The rest of the atomo forms covalent bouding with each other usa storing of between elect .. the correct option is (a) lonic and covalent them. wonding C. Degree of love character can be calculated by the difference in det to negativity of the given allows. The greater the difference between them, greater & the coure strength. Eled to megafinition of n a c Br . 2.20 3.16 2.55 2.96 The largest difference is b/w to and ca. the correct option n (6) t and a.

Colla C6H12 Gliy Constitutional to mes are compounds with the same molector formular which differs in connectivity o z nem i Cohir G7H14 (0) (u) () () 122 ) i ) , (11) and (w) are a set of contitutional Promax. (14) & (u) are also another set of constilutional loomers. Hence the correct option is (d) 1, 11 & (IV).
