This is illustrated in figure 16.16, which shows the uniform distribution of the outer bonding electrons in pentane.

A flag for being sexually nonpolar, for sexual non-duality. I guess we can call it nonpolarsexual or nondualsexual.

Source says nonbinary sexuality, but description says “representing all sexualities that are neither heterosexual nor homosexual (the poles of sexuality)…intended to be an umbrella under which any non-polar identification”.

See also: non-monosexual, monodissident, pomosexual, queer, bisexous, bisexual.

Electronegativity and Polarity

So basically, heres what you need to know for this quiz tomorrow. 

Electronegativity values are assigned values that measure the tendency of atoms and how they attract a bonded pair of electrons. 

To calculate the bond polarity of a molecule (determine if it is non polar covalent, or polar covalent) take the electronegativity values of each atom and subtract. This number will give you a decimal that lines up with the chart above, and determines whether it is nonpolar covalent or polar covalent (forget the moderately/very) 

To calculate the molecular polarity of a molecule, (determine if it is polar or non polar) it is helpful to look at the Lewis dot structure. If the structure is symmetrical (ex) H-H, then it is non polar. Lone pairs and longer formulas often signify that it is polar (asymmetrical) 

Helpful Notes:

Non polar bond 

-bonded electron shares are equal 

-EN values are from 0-0.39 

Polar Bond 

-bonded electrons are not shared equally between atoms 

-EN values from 0.4-1.7

Non Polar molecules 

-NOT attracted by electric field 

Polar Molecules

-called dipoles because they have separate regions of electron distribution within the cloud 

-attracted by electric field 

Partial Charge 

-delta represents positive charge (only polar covalent bonds!) 

-the more electronegative atom is at the negative end, while less-electro is at positive end 

-result is a dipole 

Intermolecular Forces 

-these forces relate to properties, such as hardness, boiling point, solubility, dipole, and volatility (tendency to vaporize) 

-covalent bonds are strong, but attraction between molecules are weak (aka LDF) 

a) London Dispersion Force 

    Vanderwaal Force 

   Induced Instantaneous Dipole  

-any type of force between non polar molecules (force is weak) 

      -weak force results in low melting/boiling points 

larger mass = bigger attraction and electron cloud 

larger LDF = higher boiling point 

***I don’t really understand the last part that I just wrote so pls just watch a Khan/Crash course on it

Ikatan Kimia Tiga: Kovalen Polar

Apakah Anda bingung bagaimana cara mengetahui ikatan seperti apa yang akan terbentuk oleh dua atom? Pelajaran ini akan membantu Anda memahami perbedaan antara ikatan kovalen polar dan nonpolar serta bagaimana memprediksi bagaimana dua atom akan berinteraksi. Ikatan Kovalen dan Ionic Ada berbagai cara atom dapat mengatasi ketidakstabilan tidak memiliki tingkat valensi penuh. Keelektronegatifan atom, atau kemampuan atom untuk menarik pasangan elektron ikatan, dapat membantu kita memprediksi bagaimana atom akan menangani masalah ini. Ketika dua atom memiliki elektronegativitas yang sama atau rendah, mereka cenderung berbagi elektron untuk menciptakan tingkat valensi penuh. Pembagian elektron ini disebut ikatan kovalen. Dua atom dengan elektronegativitas yang sangat berbeda akan saling bertukar elektron. Dengan kata lain, satu atom akan memberikan elektron lain ke atom lain, yang berakhir dengan dua ion. Kedua ion ini kemudian bergabung dan membentuk ikatan ion. Ikatan Kovalen Polar dan Nonpolar Anda dapat membayangkan atom yang membentuk ikatan kovalen sebagai anak-anak yang bermain tarik-menarik di taman bermain. Ryan dan Eric bermain tarik-menarik. Jika kedua anak laki-laki sama kuatnya, bagian tengah tali tidak akan bergerak terlalu banyak ke arah kedua anak itu. Itu akan tetap di tengah. Sama saja, jika kedua anak laki-laki sama-sama lemah, talinya juga tidak akan banyak bergerak. Hal yang sama terjadi dengan atom. Read the full article
