What is the vertical groups on the periodic table and the elements bonding power based on?
Vertical groups are families. Bonding power is based upon the type of bond, the position of element in periodic table.
What two groups from the periodic table can be combined to have covalent bonding?
groups 14 and 15
How many bonding groups does the central atom of CH4 have?
The central atom in CH4 is carbon, which has four bonding groups. Each bonding group is a hydrogen atom bonded to the central carbon atom.
How many groups and how many periods does the modern periodic table have hydrogen and helium should be counted as the first period.?
The periodic table has 18 groups ant 7 periods. Hydrogen and helium are considered members of the first period.
Are any what hydrogen bonds ethanol propanol butanol pentane methanol hexane?
Hydrogen bonds can form between ethanol, propanol, and methanol due to the presence of hydroxyl groups (OH). Butanol also has potential for hydrogen bonding, while pentane and hexane do not have functional groups that allow for hydrogen bonding.
What is the effect of hydrogen bonding on vibrational frequencies in case of IR spectroscopy?
Hydrogen bonding typically results in a decrease in the vibrational frequencies of the involved bonds in IR spectroscopy. This is because hydrogen bonding leads to a stronger bond, which requires more energy to vibrate. As a result, the stretching or bending frequencies of the bonds involved in hydrogen bonding are shifted to lower values in the IR spectrum compared to the same bonds without hydrogen bonding.
What is gasoline and ethanol bonding type?
Gasoline is a mixture of hydrocarbons and does not have a specific bonding type. Ethanol, on the other hand, is a type of alcohol and has hydrogen bonding due to the presence of hydroxyl (-OH) groups.
What force of attraction gives rise to the -helix?
The hydrogen bonding interactions between the amide groups of the peptide backbone in a protein contribute to the formation of the α-helix secondary structure. These hydrogen bonds create a helical pattern, stabilizing the structure by forming a coil shape. This force of attraction helps maintain the overall shape and stability of the protein.
Why does helium and hydrogen does not come in agroup of periodic table?
Helium has 2 valence electrons and hydrogen has 1 electron. So, they are placed in different groups.
Does wood have hydrogen bonds?
Yes, wood contains cellulose fibers which can form hydrogen bonds with water molecules. Hydrogen bonding occurs between the hydroxyl (-OH) groups in cellulose and water molecules.
How are the periods on the periodic table numbered?
The elements are listed in the order of how many atoms they have. For example, hydrogen is the first element on the periodic table. Hydrogen is the smallest element, and has one atom.
How do hydrogen bonds affect the viscosities of propan-1-ol ethane-12-diol and propane-123-triol?
Propane is a gas and has extremely low viscosity. Propan-1-ol has 1 OH group and can hydrogen bond and is higher viscosity. Ethane-1,2-diol has two OH groups and double the tendency to hydrogen bond and is much higher viscosity. Propane-1,2,3-triol is also known as glycerin/glycerol and is almost like a syrup as it has such high viscosity. This is because it has 3 OH groups and thus 3 sites for hydrogen bonding.
