A. Increasing halogen atom size.
B. Decreasing acid strength.
C. Shortening of the C-C bond.
D. Increasing electronegativity.
E. Higher dipole values going from F to Cl to Br.
cant paste the spartan stuff... whats the answer?!?!?
What's the question?
For fluoracetic acid the highest Boltzmann distribution is when the dihedral angle is at 0 degrees. However, going from chloro- to bromoacetic acid, an increasing dip in the Boltzmann distribution occurs at 0 degrees. What is responsible for this "dip?" (HINT: look at how the structure of the molecule changes as the halogen atom rotates around toward the hydrogen atom attached to the oxygen atom.)
I can tell you its NOT
decreasing acid strength
and its NOT
your guess is as good as mine.. : //
its increasing halogen atom size...i just answered it and thankfully got it right
Yes, it is increasing halogen atom size
It is increasing halogen atom size...
For those who care, look at the plots in Spartan and you can automatically rule out Increasing Electronegativity and higher dipole values.
