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
2-methyl-2-pentene
Explanation:
1. Identify the group that takes precedence in this case alkene hence this molecule is an alkene with a methyl group side chain.
2.Find the longest carbon chain where the functional group(alkene group in this case) has the lowest Carbon number
3.What are the side groups? One side group can be seen at carbon 2 this group is methyl
4. Naming, number separated by "," and number from letters by "-" so the compound should be
2-methyl-2-pentene
<span>Answer is: molarity of sodium hydroxide solution is c. 4 M.</span><span>
m(NaOH) = 80.0 g.
n(NaOH) = m(NaOH) ÷ M(NaOH).
n(NaOH) = 80 g ÷ 40 g/mol.
n(NaOH) = 2 mol.
V(NaOH) = 500 mL ÷ 1000 mL/L = 0.5 L.
c(NaOH) = n(NaOH) ÷ V(NaOH).
c(NaOH) = 2 mol ÷ 0.5 L.
c(NaOH) = 4 mol/L.</span>
<span>n - amount of substance.</span>
How much time it takes for the pot to boil.
Answer:
The ΔS value of HCl undergoing transitions from gas to the aqueous phase is -43.62 J/mol.
The ΔS value of HI undergoing transitions from gas to the aqueous phase is 13.47 J/mol.
Explanation:
Entropy of the reaction :
![\Delta S=[\text{Sum of entropy of products}]-[\text{Sum of entropy of reactants}]](https://tex.z-dn.net/?f=%5CDelta%20S%3D%5B%5Ctext%7BSum%20of%20entropy%20of%20products%7D%5D-%5B%5Ctext%7BSum%20of%20entropy%20of%20reactants%7D%5D)
1) Entropies the gaseous HCl molecules= 
Entropies the aqueous HCl molecules= 
The ΔS value of HCl undergoing transitions from gas to the aqueous phase is -43.62 J/mol.
2) Entropies the gaseous HI molecules= 
Entropies the aqueous HI molecules= 
The ΔS value of HI undergoing transitions from gas to the aqueous phase is 13.47 J/mol.
