The CH2OH branch in glucose,how to expand it?
Is it
    H
     |
H-C-OH
     |
   (Rest of glucose ring)

In the hundreds of images online, someone,sometime has expanded the CH2OH for the glucose molecule.  Also, by the laws of organic chemistry, those atoms always "expand" the same way, regardless of the rest of the molecule.  For example, C-H-H-H=O doesn't exist,so that's one expansion you can't get.  Can you draw some others you think you might get?

  It is correct ...remember H can never be bonded with two atoms .
