Question

use the following information to answer the next question. a list of molecules 1 - ch₃f 2 - nh₂cl 3 - cbr₄ 4 - mgbr₂ 18. match each of the compounds above with the types of bonds or forces present. contains only london dispersion forces __________ (first blank) contains only london dispersion and dipole - dipole ________ (second blank) contains london dispersion, dipole - dipole & hydrogen bonding ________ (third blank) contains ionic bonds __________ (fourth blank) (record your four - digit answer in the numerical - response section below.) your answer:

Explanation:

Step1: Analyze London - Dispersion Forces

London - dispersion forces are present in all molecules. Non - polar molecules have only London - dispersion forces. $CBr_4$ is non - polar as the bond dipoles cancel out due to its symmetrical tetrahedral shape. So, the molecule with only London - dispersion forces is $CBr_4$ (3).

Step2: Analyze London - Dispersion and Dipole - Dipole Forces

$CH_3F$ is polar due to the electronegativity difference between C and F. It has both London - dispersion and dipole - dipole forces. So, the molecule with London - dispersion and dipole - dipole forces is $CH_3F$ (1).

Step3: Analyze London - Dispersion, Dipole - Dipole and Hydrogen Bonding

$NH_2Cl$ has N - H bonds. Nitrogen is electronegative, and hydrogen bonded to nitrogen can participate in hydrogen bonding. It also has London - dispersion and dipole - dipole forces. So, the molecule with London - dispersion, dipole - dipole and hydrogen bonding is $NH_2Cl$ (2).

Step4: Analyze Ionic Bonds

$MgBr_2$ is an ionic compound formed by the transfer of electrons from Mg (a metal) to Br (a non - metal). It contains ionic bonds. So, the molecule with ionic bonds is $MgBr_2$ (4).
