<u><em>Answer:</em></u>
- Cis-1-bromo-3-tert-butylcyclohexane will give faster reaction in E2 elimination.
<u><em>Explanation:</em></u>
- E2 is known as second order reaction . Such reaction take place in a single step. E2 involve breaking of C-H and C-X bond in order to form double bond.
<u><em>Role of cis geometry:</em></u>
- The base mostly remove hydrogen which is anti-palanar to halogen. So when both group i.e bromide and tert-butyl group will be on one side, (cis), then base can abstract hydrogen easily as a result double bond formation take place so fastly.
Answer:
2Zn + PbCl4 → 2ZnCl2 + Pb
N.B: ZnCl2 is zinc chloride
Pb is lead
Explanation:
Zinc has a chemical symbol Zn while lead(IV) chloride has the chemical formula, PbCl4. Combining these two substances in a reaction will give rise to the following:
Zn + PbCl4 → ZnCl2 + Pb
However, this equation is not balanced. To balance the equation, we make sure that the atoms of each element on both sides of the reaction are equal. This is done as follows;
2Zn + PbCl4 → 2ZnCl2 + Pb
N.B: ZnCl2 is zinc chloride
Pb is lead
Answer:
Initial pressure = 157 kpa (Approx)
Explanation:
Given:
final temperature = 234 K
final pressure = 210 kpa
Initial temperature = 175 K
Find:
Initial pressure
Computation:
Initial pressure / Initial temperature = final pressure / final temperature
Initial pressure / 175 = 210 / 234
Initial pressure = 157 kpa (Approx)
