It should be

4) polar structure

Explanation:As a result of water's polarity, each water molecule attracts other water molecules because of the opposite charges between them, forming hydrogen bonds. Water also attracts, or is attracted to, other polar molecules and ions, including many biomolecules, such as sugars, nucleic acids, and some amino acids.

Which of the following compounds has the highest boiling point.
nlexa [21]
Answer:
            1-<u>Pentanol </u>has the highest boiling point.

Explanation:
                   Boiling points of given compounds are as follow,

                 1) 2-Pentanone  =  101 °C

                 2) 1-Pentanol  =  138 °C

                 3)  Pentane  =  36.1 °C

                 4)  Pentanal  =  103 °C

Pentanol has greatest boiling point as compare to others because it involes a strongest intermolecular interactions called as hydrogen bond interactions. Remaining compounds lack the direct attachement of hydrogen to most electrnegative atom like oxygen which is present in 1-Pentanol.

the balloon is inflated outdoors on a cold day in North Dakota at a temperature of -35°C to a volume of 3.0 L. The pressure rema
iragen [17]

3.75 litres is the volume of the balloon indoors at a temperature of 25°C.

Explanation:

Data given:

initial temperature of the gas in balloon  = -35°C or 238.15 K

initial volume = 3 litres

final temperature = 25 °C  or 298.15 K

final volume =?

pressure remains constant

From the data given when pressure is constant Charles' law is applied.

\frac{V1}{T1} = \frac{V2}{T2}

Rearranging the equation to know the final volume of the gas in balloon

V2 = \frac{V1T2}{T1}

V2 = \frac{3 X 298.15}{238.15}

V2 = 3.75 Litres

when the temperature of a gas is increased and pressure remains constant the volume of the gas increases.
