Which of the following cannot have hydrogen bonds? Select one: A. NH3 B. H2O C. HF D. CH3NH2 E. Which of the following cannot have hydrogen bonds? Select one: A. NH3 B. H2O C. HF D. CH3NH2 E. HCl

HCl is the compound which doesn't have hydrogen bonds. This is because of

the higher size of the chlorine atom.

There is no hydrogen bond because of the high size of the chlorine.

Chlorine have electrons with a very low density. It is also very

electronegative which explains why the formation of hydrogen bonds in the

compound HCl is not possible.

Instead, HCl has covalent bonds in which electron is shared between the

hydrogen and  chlorine to achieve a stable configuration.

E. HCl

Explanation:

Cl atom does not have enough electronegativity to make enough positive charge on H.

fe 55.85 g/mol and h2o 18.02 g/mol.

answer : third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol

explanation :

let us write down the given equations

equation 1 :

equation 2 :

equation 3 :

let us use hess's law to find out which 2 equations can be added to get the third equation.

let us reverse equation 2 and multiply it by 2. the new equation that we get is,

equation 4 :

let us add equation 1 & 4

the above equation is similar to equation 3 but has different value for dhrxn.

therefore third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol
