Draw the structural formula for 1 bromo 3 phenyl 5 heptyne
1 answer:
See Figure 4 below.
1. Draw a 7-carbon chain and number the carbon atoms (<em>Figure 1</em>).
2. Insert a triple bond between atoms 5 and 6 (<em>Figure 2</em>).
3. Attach a phenyl group to atom 3 (<em>Figure 3</em>).
4. Attach a Br to atom 1 (Figure 4).
And you have your structure.
<em>Note</em>: The C≡C triple bond takes <em>priority</em> in the naming, so we must number the chain from the other end. The correct name is
<em>7-bromo-5-phenylhept-2-yne </em>(all one word).

Answer :
The steps involved in the lewis-dot structure of are :
- First we have to determine the total number of valence electron in
.
Number of valence electrons in S = 6
Number of valence electrons in two F atom = 2(7) = 14
Total number of valence electrons = 6 + 14 = 20 electrons
- Placing a bonding pair of electrons between the atoms to form the chemical bonds.
Electrons used in bonding = 4
- The remaining electrons are used as a lone pair for central or terminal atoms to achieve an octet to finish the Lewis dot structure.
Electrons used as a lone pair = 20 - 4 = 16
