cis-1-bromo-2-methylcyclohexane on
E2 reaction yield two different cycloalkenes. This is because <span>cis-1-bromo-2-methylcyclohexane contains
two different axial beta hydrogen atoms. Therefore, base can abstract both of them forming two different products.
As shown below, the two axial beta hydrogens are specified as
Ha and Hb.
When base abstracts Ha proton then it produces </span>
3-methylcyclohex-1-ene, which is a
minor product.
And when base abstracts Hb proton the product formed is
1-methylcyclohex-1-ene. This is a
major product because it has
tri-substituted double bond hence more stable according to
Zaitsev rule.

The valence electron does the halogens possess are 7
- Valence electrons are found in the outermost energy level of an atom
- They are involved in the formation of chemical bonding with other atoms.
- The halogens elements are found in group 17 on the periodic table
- The halogens include fluorine, chlorine, bromine, iodine and astatine.
- They have seven valence electrons, so they are extremely reactive as they only need one more to fill their outer shell.
- By octet rule we can say that the electron with 8 outer most shell is full and stable.
Hence the halogens posses 7 valence electron

The answer is a, because the question is referring to partial pressures. Partial pressures are a mere sum, no halving or doubling of anything is necessary.
So, A
