One of the hydrogens in the NH3 is replaced in the first reaction by the methyl group, or -CH3. The NH3 can have more than one H substituted for it, therefore the final product frequently comprises a blend of methylamine, dimethylamine, and trimethylamine.

A halogenoalkane and ethanolic ammonia can be used in a nucleophilic substitution process to produce primary aliphatic amines like methylamine (CH3NH2).

NH3 + CH3Cl = HCl + CH3NH2

The process is challenging because any unreacted ammonia can react with the generated HCl:

NH3+HCl yields NH4Cl.

Since the N in CH3NH2 still has a single pair of electrons, it can act as a base and interact with the HCl that is created in one of the following ways:

CH3NH2+HCl becomes CH3NH3+Cl.

or as a nucleophile and react with any chloromethane that hasn't been reacted:

(CH3)2NH + HCl = CH3NH2 + CH3Cl

Can someone please help me with this asap <br><br>what is the value of d<br>​
Stella [2.4K]

The value of "d" is 80°

Explanation:

Cyclic quadrilaterals are the special group of quadrilaterals with all its base lying on the circumference of the circle. In other words, a quadrilateral inscribed in a circle is called a cyclic quadrilateral.

Cyclic quadrilateral are characterised by some special features such as

  • Sum of opposite angles of a cyclic quadrilateral is always a supplementary angle.
  • If one of the sides of a cyclic quadrilateral is produced, then the exterior angle so formed is always double of the corresponding interior angle.  

Using the property 1  

We find that since the quadrilateral is cyclic, opposite pairs must be supplementary

100° +∠D must be equal to 180°  

D=180° -100° =80°

How much water should be added to 4.3 moles of LiBr to prepare a 2.05 m solution?
arsen [322]

Answer:

2.1 kg of water

Explanation:

Step 1: Given data

  • Moles of lithium bromide (solute): 4.3 moles
  • Molality of the solution (m): 2.05 m (2.05 mol/kg)
  • Mass of water (solvent): ?

Step 2: Calculate the mass of water required

Molality is equal to the moles of solute divided by the kilograms of solvent.

m = moles of solute/kilograms of solvent

kilograms of solvent = moles of solute/m

kilograms of solvent = 4.3 mol /(2.05 mol/kg) = 2.1 kg

Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases. -google
