ESTEREOQUIMICA- QUIMICA ORGANICA

La química estereoisomérica estudia cómo las diferentes disposiciones espaciales de los átomos en las moléculas afectan sus propiedades y comportamientos. Los diastómeros y enantiómeros son dos tipos de estereoisómeros que se distinguen por su configuración espacial.

CONFIGURACION

ESTEREOQUIMICA

The first division between continents was made by ancient Greek navigators, who named them 'landmass, terra firma'.

Generally classified by convention rather than any strict criteria, nowadays seven regions are regarded as continents from a geopolitical point of view.

ESTEREOISOMERIA OPTICA

Antarctica is not only the coldest place on Earth but also the highest, driest, windiest and emptiest, completely covered with ice.

75% of the world's ice and 70% of the Earth's fresh water is located here.

Summer months of December to February give 24 hours of light, while the winter months of late March to late September are pitch dark the whole day.

There are no permanent inhabitants, except for scientists maintaining research stations in Antarctica.

ESTEREOCENTROS

Antarctica sees half a year of light and half a year of complete darkness.
Write down which months give 24 hours of light, and which are the ones that give pitch darkness the whole day.

es cualquier átomo que en el intercambio de dos grupos da lugar a un estereoisomero.
CENTROS QUIRALES
un átomo en una molécula que está unido a cuatro especies químicas diferentes, lo que permite la isomería óptica.
QUIRALIDAD

The coldest natural temperature ever recorded on Earth was recorded here.

Write it down.

a menudo esta asociada a la presencia de carbonos asimétricos.

un carbono asimétrico es un atoo de carbono que esta enlazado con cuatro sustituyentes o elementos diferentes.

The world's largest snake and the second-longest lives here.

Name this snake as well as other animals that can be found in South America.

North America has five time zones and it is the only continent with every type of climate.

North America was named after the explorer Amerigo Vespucci and is also known as the 'New World'.

The world's largest sugar exporter among the seven continents - Cuba - also called the 'sugar bowl of the world' is located here.

The world's largest freshwater lake by surface area and the third-largest freshwater lake by volume can be found here. It provides a route for the transportation of iron ore, as well as grain and other mined and manufactured materials.

Large cargo vessels called lake freighters, as well as smaller ocean-going freighters, transport these commodities across this lake.

Name this lake.

There are 23 countries that make up North America.

Name as many of you can! Don't forget about their capitals.

Australia

Australia is the world's smallest continent and is also known as an 'island continent' as it is surrounded by water on all sides.
It includes 14 countries and it is the least populated continent.

Its name comes from the Latin word 'australis' meaning 'southern' because it lies entirely on the south of the equator.

Animals

Australia is home to some animals that can't be found anywhere else in the world.

Name at least 6 of these unique animals.

Largest monolith

The largest sandstone monolith can be found here and it is one of Australia's most recognizable natural icons. It is the largest monolith in the world.

Name this rock and write down one of the characteristics it is famous for.

ACASO DE LA TALIDOMINA

Of the seven continents of the world, Africa is the second largest.

Africa comprises 54 countries and it is the hottest continent.

The equator passes through the middle of Africa and it receives direct sunlight throughout the year.

The world gets 66% of its chocolate, 50% of the gold and 95% of the diamonds from Africa.

COMO REACIONA FRENTE A OTRAS SUSTANCIAS

The world's longest river can be found here, famed for its ancient history and the archaeological sites along its shores.
This river gave rise to the early Egyptian civilization.

Name this river and add its length.
