Pick the correct pair of species that can form hydrogen bond with water. (A) CH, HCOOH (B) F, HCOOH (C) F .CH,OCH, (D) Both (B)
Xelga [282]

Answer:

(B) F⁻, HCOOH

Explanation:

(A) CH₄, HCOOH

(B) F⁻, HCOOH

(C) F⁻, CH₃-O-CH₃

The hydrogen bonds are formed when the hydrogen is found between two electronegative atoms such as oxygen (O), nitrogen (N) or florine (F).

O····H-O, F····H-O, O····H-N

(A) CH₄, HCOOH

- here methane CH₄ is not capable to form hydrogen bond with water

- formic acid HCOOH can form hydrogen bonds with water

H-C(=O)-O-H····OH₂

(B) F⁻, HCOOH

-both floride (F⁻) and formic acid can form hydrogen bonds with water

F····OH₂

H-C(=O)-O-H····OH₂

(C) F⁻, CH₃-O-CH₃

-  dimethyl-ether CH₃-O-CH₃ is not capable to form hydrogen bond with water

- floride (F⁻) can form hydrogen bonds with water

F····OH₂

Of the well-characterized elements of group 7A, which would exhibit the following properties? It reacts with the alkali metals (
dezoksy [38]

Answer:

a. fluorine

Explanation:

Fluorine is the element of group 17 and period 2. The electronic configuration of the element is 1s^22s^22p^5.

Stable oxidation state = -1 of fluorine as it gains one electron to gain noble gas configuration.

With alkali metals, which have oxidation state of +1 form ionic compound of the form, MX where X is F.

Among the halogens, fluorine forms the most stable halide because of the comparable size of the hydrogen and fluorine. Thus, it is the weakest acid when compared with other hydrogen halides.

Fluorine is the most reactive in the halogen series and thus, combines with most of the elements.

Fluorine forms inter-halogen compounds of form XA only. Example - ClF.

Hence, option a is correct.
