Please use the E/Z notation when specifying stereochemistry remembering to use parentheses and a dash. Reminder - the double bon
d takes precedence over alkyl groups when numbering the parent. (E)-5-bromo-5-ethylhept-2-ene when combined with NaOCH2CH3.
1 answer:
Answer:
(E)-5-ethylhepta-2,4-diene
Explanation:
The (E)-5-bromo-5-ethylhept-2-ene will undergo an E2 reaction. The ethoxide (⁻OCH₂CH₃) will deprotonate at the allylic position so that a conjugated diene results, which is more stable than a non-conjugated diene.
The stereochemistry in the name of the final product is indicated for only one double bond since the other has two identical groups on it.

Answer: Option (d) is the correct answer.
Explanation:
Since the given formula is . According to cross method formula, magnesium has +2 charge so,
is multiplied by 2.
Thus, 1 molecule of magnesium phosphate will contain 2 atoms of phosphorus.
Therefore, three molecules of magnesium phosphate contains following number of atoms.
- Mg = 9
- P = 6
- O = 24
Hence, we can conclude that there are 6 atoms of phosphorus in three molecules of magnesium phosphate, .
