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.

Calculate the mass of water having same number of hydrogen atoms as are present in the 32gram of methane. Please help me soon...
Ira Lisetskai [31]

Answer:

Explanation:

1 mole of methane = C + H4 = 12 + 4 = 16

32 grams of methane is 32/16 = 2 moles.

1 moles of methane contains 4 moles of hydrogen (CH4). Note the 4 in CH4

2 moles of methane = 8 moles of hydrogen.

H2O has 2 moles of hydrogen

Each mole of water contains 2 moles of hydrogen.

8 moles of hydrogen / 2 moles = 4 moles of water.

Which of the following is a list of the minimum amount of data needed for determining the molar enthalpy of solution of KCl(s) i
Gre4nikov [31]

Answer:

 (C) Mass of KCl(s), mass of H20, initial temperature of the water, and final temperature of the solution

Explanation:

molar enthalpy of solution of KCl(s) is heat evolved or absorbed when one mole of KCl is dissolved in water to make pure solution . The heat evolved or absorbed can be calculated by the following relation.

Q = msΔt where m is mass of solution or water , s is specific heat and Δt is change in temperature of water .

So data required is mass of water or solution , initial and final temperature of solution , specific heat of water is known .

Now to know molar heat , we require mass of solute or KCl dissolved to know heat heat absorbed or evolved by dissolution of one mole of solute .

Using the periodic table to locate each element, write the electron configuration of(c) Re.
Aleksandr [31]

Rhenium is a chemical element with the symbol Re and atomic number 75. The electron configuration of Re is [Xe] 6s^{2} 4f^{14} 5d^{5}.

<h3>How to write an electronic configuration?</h3>

1. Identify the given element and its atomic number from the periodic table.

2. Write the electron configuration by the energy level and the type of orbital first, then the number of electrons present in the orbital as superscript.

The easiest way to write the electronic configuration for any element is by   using a diagonal rule for electron filling order in the different subshells according to the Aufbau principle.

The 3 rules for writing the electron configuration in the orbital box diagram are – the Aufbau rule, the Pauli-exclusion rule, and Hund's Rule.
