What increases acidity more, nitrile group or chloride group?

lozanna [386]

Answer:

The nitrile group

Explanation:

The nitrile group contains the C≡N bond. It should be recalled that triple bond is highly electronegative and withdraws electrons from the C-H bond more effectively than the halogen atom.

The higher effectiveness of the C≡N bond at electron withdrawal greatly reduces the electron density of the C-H bond thereby making the hydrogen atom of the bond highly labile

A reaction of a hydrocarbon, in which carbon dioxide and water are produced, is classified as a

klasskru [66]

This is a combustion reaction. Any reaction in which a hydrocarbon decomposes into carbon dioxide and water is classified as combustion. The energy used for the decomposition usually comes from intense heat, which is why combustion of a hydrocarbon almost always is associated with a source of fire.

Write the formulas of the following compounds:

NemiM [27]

Answer:

(a) barium chloride : BaCl₂ [the cation is barium and anion chloride]

(b) magnesium-nitride : Mg₃N₂ [Mg is cation and N anion]

(d) nitrogen trichloride : NCl₃

(e) dinitrogen trioxide : N₂O₃ [two nitrogens and three oxygen]

(f) tin(IV) chloride : SnCl₄

Explanation:

The formula of a compound comprises of the symbol of all the elements.

The element or ion having positive charge is written first followed by anion.

The number of any element is represented as subscript in the formula.

(a) barium chloride : BaCl₂ [the cation is barium and anion chloride]

(b) magnesium-nitride : Mg₃N₂ [Mg is cation and N anion]

(d) nitrogen trichloride : NCl₃

(e) dinitrogen trioxide : N₂O₃ [two nitrogens and three oxygen]

Murljashka [212]

Both the assertion and reasoning are true and the reason correctly explains the assertion.

Option i.

<h3><u>Explanation:</u></h3>

Structural isomers are the different compounds that are actually same mother molecule but with different structure. This gives the same compound with different physical and chemical properties. The structural isomers can even make an isomer solid and another isomer liquid at a particular temperature.

The structures that are given here, the first structure is a n butane, and the second structure is of a 1 methyl propane,or also called as isobutane.

Both the compounds are having same molecular formula of C4H10. But they do have different numbers of primary, secondary and tertiary carbon atoms due to differences in structures.
