Which of the following molecules is/are expected to form hydrogen bonds in the liquid state or solid state: h2so4, hf, ch3oh, ch2o (formaldehyde)

, HF and are expected to form hydrogen bonds in the liquid or solid state.

Explanation:

In liquid or solid state, intramolecular H-bonding takes place.

H-bonding is only formed when H atom remain attached with electronegative atoms such as O, F and N.

Formaldehyde contains no H atom attached to above mentioned electronegative atoms. Therefore formaldehyde does not form any hydrogen bonding in liquid or solid state.

All other given molecules contains H atom attached with any of the above mentioned electronegative atoms. Therefore all the molecules except formaldehyde is expected to form hydrogen bond in the liquid or solid state.

Lewis structures are given below.

introduction of a drug directly into the respiratory tract is a form of inhalation administration.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
