X why is cyano group called as anambident group?​

Chemistry
1 answer:
Ira Lisetskai [31]3 years ago
3 0

Answer:

Both the C and the N can participate in reactions  

Explanation:

The word ambident comes from two Latin words that mean "both teeth".

An ambident group can react at two different sites to form products.  

For example, the cyano group has two major resonance structures (see below).

The hybrid has two different ends, each with a lone pair and a partial negative charge.

Thus, it can react to form CH₃CN by having the C attack, or CH₃NC by having the N attack.

What volume of a 3.95 M
KATRIN_1 [288]

0.227L is the volume of a 3.95 M potassium chloride solution that would be needed to make 325 mL of a 2.76 M solution by dilution.

<h3>What are moles?</h3>

A mole is defined as 6.02214076 × 10^{23} of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.

Moles of KCl in new solution

0.325dm³ x (2.76mol/dm³)

= 0.897mol.

Hence volume needed

0.897mol ÷(3.95mol/dm³)

= 0.227dm³ or 0.227L.

What is Charles' law formula?
mestny [16]
In the 1800s a French scientist named Jacques Charles made discoveries regarding the effect of temperature on gases. Charles law states that at a constant pressure the volume of a given mass of gas is directly proportional to the absolute temperature.

A flexible container at an initial volume of 6.13 L contains 6.51 mol of gas. More gas is then added to the container until it r
aivan3 [116]

Answer:

the final mole of the flexible container = 12.92 moles

Explanation:

Given that :

initial volume of a flexible container = 6.13 L

initial mole of a flexible container = 6.51 mol

final volume of a flexible container = 18.3 L

final mole of a flexible container = ???

Assuming the pressure and temperature of the gas remain constant, calculate the number of moles of gas added to the container.

Therefore,

n= \dfrac{V_2*n_1}{V_1}

n= \dfrac{18.3*6.51}{6.13}

n = 19.43

n=n_1+n_2

19.43 = 6.51 + n₂

n₂ = 19.43 - 6.51

n₂ = 12.92 moles

Thus; the final mole of the flexible container = 12.92 moles

Calculate the percentage of water of crystallisation in MgSO⁴ 7H²O
Bas_tet [7]

Answer:

Formula of EPSOM salt = MgSO4.7H2O

molecular mass of MgSO4.7H2O = atomic mass of Mg + atomic mass of S + 4 × atomic mass of O + 7 { 2 × atomic mass of H + atomic mass of O }

= 24 + 32 + 4× 16 + 7{ 2 × 1 + 16 } g/mol

= (24 + 32 + 64+ 126 ) g/mol

= 246 g/mol

molecular mass of total water = 7 × ( 2× atomic mass of H + atomic mass of O )

= 7 × 18 = 126 g/mol

now ,

% mass of H2O in EPSOM salt = {total molar mass of H2O/molar mass of Epsom salts }× 100

= {126/246 } × 100

= 12600/246

= 51.21 %
