Molecular structure? There are two Hydrogens attach to oxygen atom in a bent structure http://www.dichotomistic.com/images/water%202.gif

I had a dream to begin my commerce, but I didn't have got enough amount of money to do it. Thank goodness my close fellow recommended to use the home loans. Thus I received the sba loan and realized my desire.
To determine the molecular structure around the oxygen in water and around the carbons in ethanol, we need to understand the Lewis dot structure and use it to determine the arrangement of atoms and bonding within the molecules.
1. The Molecular Structure of Water (H2O):
In water (H2O), each hydrogen atom (H) is bonded to the oxygen atom (O). The Lewis dot structure for water shows that oxygen has two pairs of unshared electrons (lone pairs) and two shared pairs of electrons (bonding pairs). The arrangement is bent or V-shaped, with the oxygen atom at the center and the hydrogen atoms forming a bond angle of approximately 104.5 degrees with the oxygen atom. The molecular structure of water can be represented as H-O-H.
2. The Molecular Structure of Ethanol (C2H5OH):
In ethanol (C2H5OH), carbon atoms (C) are bonded to hydrogen atoms (H) and one oxygen atom (O). The Lewis dot structure for ethanol shows each carbon atom forms four bonds: three with hydrogen atoms and one with the oxygen atom. The oxygen atom has two lone pairs of electrons. The molecular structure of ethanol can be represented as CH3-CH2-OH, where there is an -O- (oxygen) atom bonded between two carbon atoms, and each carbon atom is bonded to three hydrogen atoms.
Remember, the Lewis dot structure is a simplified representation of molecular bonding, and it provides a visual guide for understanding the arrangement of atoms and electrons within a molecule.
