Answer:

How about this?

Explanation:

(1) Halogenation of an alkane

Reaction with Br₂ in the presence of UV light to give bromocyclopentane.

(2) Dehydrohalogenation

Reaction with hot alcoholic KOH to give cyclopentene.

(3) Allylic bromination

Reaction with N-bromosuccinimide and a drop of HBr(aq) gives

3-bromocyclopentene.

What phenomenon does the Coriolis effect arise from making it so we see more than two large convection cells on Earth? Curvature
vredina [299]

Answer:

The Coriolis effect is caused by the rotation of the earth around its own axis.

Explanation:

The Coriolis effect arises from the fact that different latitudes of the earth's surface rotate at different speeds. The path of wind on earth is deflected by the Coriolis effect. As things move over the earth, they meet different speed areas, which causes the Coriolis Effect to divert their route.

Thus, The Coriolis effect is caused by the rotation of the earth around its own axis.

A reasonable pka for a weak base is:<br><br> 10.3<br><br> 0.9<br><br> 5.8<br><br> 7.4<br><br> 13.1
andriy [413]

Answer:

0.9

Explanation:

The pka represents the force by which the molecules need to dissociate for the acids ,

Hence , lower the pka stronger will be the acid and that therefore will  dissociate completely and vice versa , for a weak acid higher the pka .

And in case of a base , it will be completely reversed , lower pKa , weaker base ,

and higher pKa , stronger base .

From the data of the question ,

0.9 is the lowest value of the pKa , hence , weakest base .

The pH of a solution is 2.0. Which statement is correct?
mamaluj [8]

Answer:

pH + pOH = 14,  [H₃0⁺] [0H⁻] = 10⁻¹⁴

Explanation:

When it comes to questions involving pH, the equations used are;

[H₃0⁺] [0H⁻] = 10⁻¹⁴

This equation shows the concentration of hydroxonium ions alongside that of the hydroxide ions.

pH + pOH = 14

If the value of either the pH of the pOH is know,one can calculate the value of the other using this equation.
