I have a picture of Cipro in the attachement and in one of the questions it asks

How may sp² hybridized methines does Cipro have?

I think the answer is one is this correct if not pleae explain.


Thank you

.doc files can have nasty macros. Trasnfer everything into notepad and save it as a .txt and that can be uploaded.

This is a structure of ciprofloxacin

Thank you for helping me find the picture.

I hope the picture can help someone point me in the right direction for this question:

How may sp2 hybridized methines does Cipro have?

I think the answer is one is this correct if not pleae explain

Again Thank you

first of all: ask yourself what is a methine?

then: what does sp2 hybridization tell you?

[jena]

Hi,

A methine is C-H and sp2 hybridization refers to have a trigonal shape, with an ideal angle of 120 degrees.

So would the answer in this case be zero is this correct.

Thank you

Hint - try to add all hydrogen atoms to above formula - 16 H are missing

Hi,

I looked it over again is the answer six. If not am I even close to the answer.

Thank you  

[dexangeles]

hint: maybe it's easier if you put the missing carbons and hydrogens in so you can visualize it more

[AWK]

May be, this time you can calculate Car-H methines correctly

I'm giving it one more try with the answer is it 3

thank you
