Answer:
Homologous series is defined as a systematic order of structurally similar organic compound containing same functional group in their family and two adjacent members differ in their molecular formula by -CH2 unit.
Characteristics:
1.Various members of homologous series contain same functional group.
2.Various members of homologous series can be represented by common formula.
3. All members of a homologous series have almost similar chemical properties.
4. All members have common method of preparation.
5.Two successive members of homologous series have different chain length or difference in their molecular formula by -CH2 unit.
6.The members of homologous series show different physical properties.
Answer:
b because no death and no emigration
Explanation:
Answer:
0.9
Explanation:
The pka represents the force by which the molecules need to dissociate for the acids ,
Hence , lower the pka stronger will be the acid and that therefore will dissociate completely and vice versa , for a weak acid higher the pka .
And in case of a base , it will be completely reversed , lower pKa , weaker base ,
and higher pKa , stronger base .
From the data of the question ,
0.9 is the lowest value of the pKa , hence , weakest base .
