Why does acetic acid have a high boiling point?
Comparing to different kinds of substance, the reason is different. But basicly because that between molecules of the acid, there is a force call hydrogen bond. It is not a chemical bond in the traditional sense, but more of a static electroforce. As the acetic acid base pulls electron from the hydrogen, electrons accumulate around the base making it a negative atmosphere- or a "pole". And the core of the hydrogen atom is exposed. As the core of any atom is positively charged, it becomes another "pole". the "-" pole of one molecule will attract "+" poles from different molecules. This makes molecules difficult to break away. Thus, the high boilling point.
How do dipole dipole forces affect the melting and boiling points of substances?
Think relationships here... really London Dispersion Force is like an acquaintance, Dipole Dipole is like boyfriend/girlfriend and Hydrogen Bonding is like marriage. Now out of the three London dispersion is the easiest to break the bonds, Di Pole Di pole are a little harder to break up and Hydrogen bonding are the hardest to break up the bonds. Hydrogen Bonding will always have the strongest bond. London dispersion is when for a split second their is a short attraction and doesn't last long. It is very weak therefore making this non- polar. Dipole Dipole means 2 opposite sides. Positive and negative charges. This molecule is a Polar molecule. Hydrogen Bonding is a Polar molecule which attaches itself to either N,O,or F. A melting point takes a low energy to melt so the bonds are weak. the higher the boiling temperature the stronger the bonds. Think H20. Melting is comparing how hard it is to separate the molecules. Same Concept. Ex.1.) CH4 / LiCl CH4 more soluable / LiCl low soluability CH4 low melting point / LiCL higher melting point CH4 low boiling point/ LiCL Higher boiling point CH4 London Dispersion / LiCl Dipole Dipole Example2: H2O / NaCl H2O high boiling point/ NaCl lower boiling point H2O Hydrogen bonding/ NaCl Dipole Dipol
What does the polar look like?
the polar bear has hair that appears to be white, but every hair is actually almost like transparent. they have black noses, black eyes, and rounded ears. they have sharp canine teeth and oily, water repellent fur. under neath this fur is black skin, Not blue!
When NaCl is dissolved in water negative end of the water molecules is attracted towards what?
Ion-dipole attraction dictates that the negative pole of a water molecule will be attracted to the sodium cation and the positive pole of a water molecule will be attracted to the chloride anion.
Differentiate between monopole and dipole?
A monopole is a single charge or magnetic pole that generates a field, such as an electric charge or a north or south magnetic pole. A dipole consists of two equal and opposite charges or poles separated by a distance, producing a dipole moment that creates a characteristic field pattern. In essence, a monopole has one pole, while a dipole has two poles.
Is the north pole made of water?
The North pole is an imaginary point on the floating ice sheet of the Arctic Ocean.
What is the northernmost part of the world?
The northernmost point of Earth is the geographic North Pole, in the Arctic Ocean. It defines geodetic latitude 90° North, as well as the direction of true north.The North Pole is located in the middle of the Arctic Ocean. The water is almost permanently covered with shifting sea ice.
What point of earth is farthest from the north Pole?
The South Pole is the farthest point from the North Pole.
The point farthest north on the earth is called?
The point farthest north on Earth is called the North Pole. It is located at 90 degrees north latitude.
What is the northernmost point on the earth?
The northernmost point on Earth is the geographic North Pole. It is located at 90 degrees latitude north.
What is the nothermost point in the world called?
The northernmost point on the Earth is the North Pole. It is also known as the Geographic North Pole or the Terrestrial North Pole.
Which baseline runs from any point on the earth surface to the north pole?
True north runs from any point on the Earth's surface to the North Pole.
What is the closest ocean to the North Pole?
The North Pole is in the middle of the Arctic Ocean. The Arctic Ocean at this point is not water, but ice. It is a frozen ocean .
The point farthes north on the globe is what?
The North Pole is the point farthest north on the globe, located at a latitude of 90 degrees north.
Which pole is Guyana nearest to?
Every point in Guyana is closer to the north pole than any point in Guyana is to the south pole.
What is the northernmost and southernmost point in the world called?
The northernmost point of Earth is the geographic North Pole, in the Arctic Ocean. It defines geodetic latitude 90° North, as well as the direction of true north. The North Pole is located in the middle of the Arctic Ocean. The water is almost permanently covered with shifting sea ice.The southernmost point of the world is the geographic South Pole, which is on the continent of Antarctica. The geographic coordinates of the South Pole are usually given simply as 90°S. It's on Antarctica, which is a featureless, barren, windswept, icy plateau.
What is located at 90N latitude?
"90° North latitude" describes a single point on earth. That point is commonly referred to as the "north pole".
