Hello!
From tables, we know that the
pKa for Methylamine CH₃NH₂ is 10,61. Now, we can apply the
Henderson-Hasselbach's equation and clear for the ratio of CH₃NH₂ to CH₃NH₃Cl
So, the ratio of CH₃NH₂ to CH₃NH₃Cl should be
0,32Have a nice day!
Answer:
Scheme is attached
Explanation:
When 3‑bromopentane reacts with hydroxide, (Z)-pent-2-ene will produce through E 2 (Z)-pent-2-ene.
Mechanism
Hydroxide ion (OH⁻ ) is a strong nucleophile so it abstract the proton from carbon next to the carbon attached with bromine.
The the carbon next to carbon of bromine gets -ve charge, mean while it shares its electrons with the carbon having bromine and make a double bond.
As bromine is a good leaving group so it easily gets detached from carbon, so that carbon comes to its normal state.
As a result (Z)-pent-2-ene will produce. we call it Z because mostly trans products will form.
The electric Configuration of chlorine can be written as 2,8,7 electrons are distributed in the shells K,L,M respectively.
Hi!
Magnets attract with opposite poles. The reason is the North pole of a magnet's magnetic lines (if that makes any sense) generally flow inwards, making it pulling in, and the South pole's magnetic lines flow outwards, pushing out. If you align two magnets with the same poles together, they will always repel, because they will be flowing in different directions.
However, if you align a north and a south pole together, they will work together, and attract.
Therefore, if you place two magnets randomly, and they're close enough, they'll align so that the north pole of one magnet faces the south pole of the other magnet, or choice A.
