True would be your answer
H3C-CH2-CH2-CH3
<span>ion-ion bonds: not an ion </span>
<span>ion-dipole bonds: not an ion and no dipole </span>
<span>dipole-dipole bonds: butane is nonpolar, so no dipole </span>
<span>Hydrogen bonds: does not contain H bonded to F,O, or N </span>
<span>therefore the only intra-molecular bonds remaining are the weakest of the weak - london dispersion forces (aka Van Der Waals). These are randomly induced dipole attractions that happen when the electrons that move around randomly just happen to have a higher concentration at one end of the molecule. This causes dipoles to form in adjacent molecules, which induce dipoles in molecules next to them. these forces are very weak, but still play a part in raising the boiling point of butane.</span>
Answer:

5H
1O
1H
I think you wrote the formula for ethanol wrong but still with the one you wrote it is still 9.
Answer:
9. 8.2x10¹⁴ Hz
Explanation:
Wavelength λ = 366 nm
Formula: Frequency = C / λ
To find the wavelength in m,
1 nm = 1.0x10⁻⁹ m
So, 366 nm = ?
= 3.66x10⁻⁷ m
Frequency = 3.0x10⁸m.s-1 / 3.66x10⁻⁷ m
= 8.2x10¹⁴ s-1
