Which of these could be separated by distillation or filtration
2 answers:
Answer: Option (B) is the correct answer.
Explanation:
A process where solute or solid particles which are present in a liquid or gas are separated out with the help of a filter medium like filter paper is known as filtration process.
For example, sand can be separated out from water by using a filter paper.
Components of a mixture can never combine chemically with each other.
Whereas, an element is a substance which contains only one type or kind of atoms.
For example, a pure zinc will contain only atoms of zinc.
A compound is defined as the substance in which different elements are chemically combined together in a fixed ratio by mass.
For example, is a compound and elements are present in 1:4 ratio.
A compound can be divided into its constituent or simpler substances.
Thus, we can conclude that a mixture could be separated by distillation or filtration.

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
