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).

When two objects are near each other, increasing one object’s mass would cause the gravitational force of the object to increase.
The formula for gravitational force (<em>F</em>) is
where <em>m</em> and <em>M</em> are the masses of the two objects, <em>d</em> is the distance between their centres, and <em>G</em> is the gravitational constant.
If we hold <em>M</em> and <em>d</em> constant, we can write
, where
Thus, gravitational force is <em>directly proportional</em> to the mass of the object.
If you increase the mass of an object, you increase its gravitational force.
