How can you tell if a covalent bond is polar or nonpolar? Covalent bonds that are polar have an unequal sharing of a pair of electrons. This would be determined by an electronegativity difference of the two elements falling between 0.4 and 1.7. Non-polar bonds have less than 0.4 electronegat...

What are the 4 organic molecules and relate the molecular structure of each? What type of bonds hold the two chains of DNA together in a DNA molecule? A) hydrogen B) polar covalent C) nonpolar covalent D) ionic E) more than one of these ...
Water is polar, meaning its overall charge is unevenly distributed. Hydrogen gets pulled towards the oxygen. Hydrogen is partially positive, so the region on hydrogen is partially positive. (Oxygen is negative) What type of bonds are between the hydrogen and the oxygen in a water molecule?
The purine and pyrimidine bases form hydrogen bonds to keep the two rails of the DNA molecule together. Adenine and thymine form two hydrogen bonds while guanine and cytosine form three. Hydrogen bonds are electrostatic forces between electrically charged parts of a polar molecule rather than chemica...

D) 6350 km is the wrong answer because it won't create an oblate spheroid.Hence Option D is incorrect.Hence the correct answer is option ‘B’.Note:Those involved within the study of measuring the planet, called geodesists. The polar regions are the fore...
All lipids are made up of the same atoms: carbon (C), hydrogen (H) and oxygen (O). Lipids contain the same elements that make up carbohydrates but in different proportions. Lipids have a large proportion of carbon and hydrogen bonds and a small proportion of oxygen atoms. Although the st...
Nikki has a master's degree in teaching chemistry and has taught high school chemistry, biology and astronomy. Defining Dipoles and Dipole Moments Dipolesform when the electrons are unevenly shared in the covalent bonds, creating partial positive and negative charges on all atoms involved. The atom...
Chemistry vocabulary and Chemistry glossary are different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, structure, behaviour, and changes that occur ...
