hi,I have completed this but says I made 1 error,may i please ask which 1 is fillied in incorrectly?

-fillied in words are in brackets


1)H2S : ( bent) electron-domain geometry with (2 nonbonding pairs )on S will cause the bond angle to deviate from ideal (109.5)∘


2)BCl3: ( trigonal planar )electron-domain geometry with( 0 nonbonding pairs )on B. We confidently predict (120∘ )angles.


3)CH3I: :( tetrahedral) electron-domain geometry with( 0 nonbonding pairs) on C. Because the bonding electron domains are not exactly the same, we predict some deviation from ideal (109.5)∘ angles.


4)CBr4:( tetrahedral) electron-domain geometry with( 0 nonbonding pairs )on C. We confidently predict (109.5)∘ angles.


5)TeBr4: ( trigonal bipyramidal) electron-domain geometry with (1 nonbonding pair )on Te will cause the bond angles to deviate from ideal values.
