Solution :
First we have to calculate the moles of .
Now we have to calculate the moles of NaBr.
The balanced chemical reaction is,
From the balanced reaction we conclude that
As, 2 moles of react with 2 moles of
So, 2.87 moles of react with 2.87 moles of
Now we have to calculate the mass of NaBr.
Therefore, the mass mass of is, 295.323 grams
Answer: The IUPAC name of is 5-chloro-2-pentyne
Explanation:
1. First select the longest possible carbon chain. For the number of carbon atom, we add prefix as 'meth' for 1, 'eth' for 2, 'prop' for 3, 'but' for 4, 'pent' for 5, 'hex' for 6, 'sept' for 7, 'oct' for 8, 'nona' for 9 and 'deca' for 10.
2. The longest possible carbon chain should contain all the bonds and functional groups.
3. The numbering is done in such a way that the carbon containing the functional group or substituent gets the lowest number. Triple bond is given priority over substituent halogen.
4. The naming of alkane is done by adding the suffix -ane, alkene by adding the suffix -ene, alkyne.
Thus the IUPAC name of is 5-chloro-2-pentyne
