Answer:
O D. It has an -OH group attached to the end of the molecule.
Explanation:
Some alcohols have hydroxyl group (OH) attached to the end of a molecule and some have it attached as a branch on the molecule

- R is aryl or alkyl group
- OH is hydroxyl group
Answer:
The correct answer is the final pair: C4H10 and C2H5
Explanation:
Took the test and it was right. :)
(4) total number of valence electrons, because they exist in the same group.
Generally, the top elements in group 16 will have a charge of -2, although the entire group isn't standardized.
Ca(OH)₂ = Ca²⁺ + 2OH⁻
[OH⁻]=2c{Ca(OH)₂}
pH=14+lg[OH⁻]
pH=14+lg(2c{Ca(OH)₂})
pH=14+lg(2*0.0075)=12.18
