Answer:
Explanation:
Seven of these isomers having similar pKa values are as follows
1) CH₃ -CH(CH₃)-CH(NO₂)-CH₃
2 ) CH₃ -(CH₂)-CH(NO₂)-CH₂-CH₃
3 ) CH₃ -CH₂-CH₂-CH₂-CH₂-NO₂
4 ) CH₃ -CH₂-CH₂-CH(NO₂)-CH₃
5 )CH₃ -CH(CH₃)(NO₂)-CH₂-CH₃
6 ) CH₃ -CH(CH₃)-CH₂-CH₂-NO₂
7)CH₃ -CH₂-CH₂-CH(CH₃)-NO₂
CH₃-C(CH₃)₂-NO₂
The last isomer has different PKa value because of tertiary carbon attached to nitro group.
Answer:
Anywhere there is moist soil and dead plant material,rainy forest areas, on land and in freshwater
Explanation:
Ca= 2 ve
Be=2 ve
Mg=2 ve because they are in Group 2a.
They are slightly less reactive than Group 1a, but more dense that Group 1a.
The potential energy the bucket started with transforms into kinetic energy as it moves.
